Wu, Xiaozeng;Cui, Yang research published 《 Synthesis of azetidine medicinal intermediate》, the research content is summarized as follows. Two ways in synthesis of pharmaceutical intermediate 1-(tert-butyl)-3-aminoazetidine were investigated by 1-(tert-butyl)-3-hydroxyazetidine as raw materials, sodium azide and phthalimide potassium salt as the ammonia source, and experiments operability, security, yield and post-processing level of them were studied. Experiments showed that when using azide as the ammonia source to replace the hydroxyl with azido, then adding zinc powder can be reduced to the product, obtained 70% yield. However, sodium azide may be toxic, the operation is more difficult due to its explosion when heat or vibration. When potassium phthalimide was used as the ammonia source, the product was obtained by hydrazinolysis the tert-ammonia solution in hydrazine hydrate. The yield was 63%, though lower than the former method, but the experiment could be operational very strong, safe and simple post-processing.

72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde.

Proprotein convertase subtilisin-like/kexin type 9 (PCSK9) is a key regulator of plasma LDL-cholesterol (LDL-C) and a clin. validated target for the treatment of hypercholesterolemia and coronary artery disease. Starting from second-generation lead structures such as 2, we were able to refine these structures to obtain extremely potent bi- and tricyclic PCSK9 inhibitor peptides. Optimized mols. such as 44 demonstrated sufficient oral bioavailability to maintain therapeutic levels in rats and cynomolgus monkeys after dosing with an enabled formulation. We demonstrated target engagement and LDL lowering in cynomolgus monkeys essentially identical to those observed with the clin. approved, parenterally dosed antibodies. These mols. represent the first report of highly potent and orally bioavailable macrocyclic peptide PCSK9 inhibitors with overall profiles favorable for potential development as once-daily oral lipid-lowering agents. In this manuscript, we detail the design criteria and multiparameter optimization of this novel series of PCSK9 inhibitors.

Martin;Molteni, Valentina;Liu, Bo;Phimister, Andrew;Joseph, Sean B.;Laffitte, Bryan research published 《 Discovery of Tropifexor (LJN452), a Highly Potent Non-bile Acid FXR Agonist for the Treatment of Cholestatic Liver Diseases and Nonalcoholic Steatohepatitis (NASH)》, the research content is summarized as follows. The farnesoid X receptor (FXR) is a nuclear receptor that acts as a master regulator of bile acid metabolism and signaling. Activation of FXR inhibits bile acid synthesis and increases bile acid conjugation, transport, and excretion, thereby protecting the liver from the harmful effects of bile accumulation, leading to considerable interest in FXR as a therapeutic target for the treatment of cholestasis and nonalcoholic steatohepatitis. We identified a novel series of highly potent non-bile acid FXR agonists that introduce a bicyclic nortropine-substituted benzothiazole carboxylic acid moiety onto a trisubstituted isoxazole scaffold. Herein, we report the discovery of 1 (tropifexor, LJN452), a novel and highly potent agonist of FXR. Potent in vivo activity was demonstrated in rodent PD models by measuring the induction of FXR target genes in various tissues. Tropifexor has advanced into phase 2 human clin. trials in patients with NASH and PBC.

Vosahlo, Petr;Schulz, Jiri;Cisarova, Ivana;Stepnicka, Petr research published 《 Cyclopalladation of a ferrocene acylphosphine and the reactivity of the C-H activated products》, the research content is summarized as follows. Acylphosphines are an attractive subclass of phosphine ligands with specific reactivity and ligating properties. This study describes the synthesis of a ferrocene-based acylphosphine, FcC(O)PPh₂ (1, Fc = ferrocenyl), the corresponding phosphine chalcogenides FcC(O)P(E)Ph₂ (E = O, S and Se), and palladium(II) complexes resulting from the orthometalation of 1, viz. [Pd(μ-X)(1 – H)]₂ (2-X, where X = Cl, Br and I), which in turn serve as a convenient entry point to a range of monopalladium complexes. Thus, the cleavage of 2-X with phosphines, 4-(dimethylamino)pyridine and in situ-generated 1,3-dimesitylimidazolin-2-ylidene (L) provided complexes [PdX(L)(1 – H)] (3–5), which are typically obtained as single isomers by crystallization but undergo spontaneous isomerization in solution leading to equilibrium mixtures of cis and trans isomers. Upon treatment with sodium acetylacetonate (Na(acac)), 2-Cl was transformed into [Pd(acac)(1 – H)] (6), which reacted with (diphenylphosphino)acetic acid under proton transfer to give [Pd(Ph₂PCH₂CO₂-κ²O,P)(1 – H)] (7), while the reaction with allylating agents produced the π-allyl complex [Pd(η³-C₃H₅)(1 – H)] (9). Compound [PdCl(PMe₃)(1 – H)] was further used to prepare a series of diorganopalladium complexes [Pd(R)(PMe₃)(1 – H)] (8; R = Me, 4-C₆H₄Me, 4-C₆H₄CF₃, CH:CHC₆H₄Me-4 and CCC₆H₄Me-4). All compounds were structurally characterized using spectroscopic methods and, in most cases, also by X-ray diffraction anal. The structural data indicated the rigidity of the Pd(1 – H)⁺ fragment and revealed variations in the Pd-donor distances dictated by an interplay between the trans influence and steric demands of the ligands surrounding Pd(II). Moreover, some compounds were studied by DFT to rationalize their isomerization equilibrium and electrochem. properties, which were examined by cyclic voltammetry.

G-protein-coupled receptor 119 (GPR119) is expressed predominantly in pancreatic β-cells and in enteroendocrine cells in the gastrointestinal tract. GPR119 agonists have been shown to stimulate glucose-dependent insulin release by direct action in the pancreas and to promote secretion of the incretin GLP-1 by action in the gastrointestinal tract. This dual mechanism of action has generated significant interest in the discovery of small mol. GPR119 agonists as a potential new treatment for type 2 diabetes. Herein, the authors describe the discovery and optimization of a new class of pyridone containing GPR119 agonists. The potent and selective BMS-903452 I was efficacious in both acute and chronic in vivo rodent models of diabetes. Dosing of I in a single ascending dose study in normal healthy humans showed a dose dependent increase in exposure and a trend toward increased total GLP-1 plasma levels.

Tafazolian, Hosein;VenkatRamani, Sudarsan;Tsay, Charlene;Schrock, Richard R.;Mueller, Peter research published 《 Syntheses of Molybdenum and Tungsten Imido Alkylidene Complexes that Contain a Bidentate Oxo/Thiolato Ligand》, the research content is summarized as follows. 3,3′,5,5′-Tetra-tert-butyl-2′-sulfanyl[1,1′-biphenyl]-2-ol (H₂[^tBu₄OS]) was prepared in 24% yield overall from the analogous biphenol using standard techniques. Addition of H₂[^tBu₄OS] to Mo(NAr)(CHCMe₂Ph)(2,5-dimethylpyrrolide)₂ led to formation of Mo(NAr)(CHCMe₂Ph)[^tBu₄OS], which was trapped with PMe₃ to give Mo(NAr)(CHCMe₂Ph)[^tBu₄OS](PMe₃) (1-PMe₃). An X-ray crystallog. study of 1-PMe₃ revealed that two structurally distinct square pyramidal mols. are present in which the alkylidene ligand occupies the apical position in each. Both isomers 1-PMe₃-A and 1-PMe₃-B are disordered. Group 6 element complexes Mo(NAd)(CHCMe₂Ph)(^tBu₄OS)(PMe₃) (2-PMe₃; Ad = 1-adamantyl) and W(NAr)(CHCMe₂Ph)(^tBu₄OS)(PMe₃) (3-PMe₃) were prepared using analogous approaches. Reaction of 1-PMe₃ with ethylene (1 atm) in benzene within 45 min gave an ethylene complex Mo(NAr)(^tBu₄OS)(η²-C₂H₄) (4) that is isolable and relatively stable toward loss of ethylene below 60°. An X-ray study shows that the bond distances and angles for the ethylene ligand in 4 are like those found for bisalkoxide ethylene complexes of the same general type. Complex 1-PMe₃ in the presence of one equiv of B(C₆F₅)₃ catalyzes the homocoupling of 1-decene, allyltrimethylsilane, and pinacol allylboronate at ambient temperature The complexes 1-PMe₃, 2-PMe₃, and 3-PMe₃ all catalyze the ROMP of rac-endo,exo-5,6-dicarbomethoxynorbornene (rac-DCMNBE) in the presence of B(C₆F₅)₃, but the polyDCMNBE that is formed has a random structure.
