Jiang, Binyang;Shi, Shi-Liang research published 《 Pd-Catalyzed Cross-Coupling of Alkylzirconocenes and Aryl Chlorides》, the research content is summarized as follows. The first Pd-catalyzed aryl-alkyl cross-coupling of alkylzirconocenes and aryl halides was reported. A com. available N-heterocyclic carbene (IPr) as the ligand for palladium catalyst was critical to enable the challenging process. This mild protocol does not require base additives and tolerated a broad scope of both coupling partners bearing various functional groups and heterocycles. Moreover, both terminal and internal alkenes were applicable, and the latter underwent “chain walking”, giving the terminal coupling product exclusively. Preliminary mechanistic studies revealed a precatalyst activation pathway and inhibited β-H elimination due to steric bulk of NHC ligand.

Reference of 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. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

Jin, Yuan;Orihara, Kensuke;Kawagishi, Fumiki;Toma, Tatsuya;Fukuyama, Tohru;Yokoshima, Satoshi research published 《 Total Synthesis of Haliclonin A》, the research content is summarized as follows. The total synthesis of haliclonin A was accomplished. Starting from 3,5-dimethoxybenzoic acid, a functionalized cyclohexanone fused to a 17-membered ring was prepared through a Birch reduction/alkylation sequence, ring-closing metathesis, intramol. cyclopropanation, and stereoselective 1,4-addition of an organocopper reagent to an enone moiety. Reductive C-N bond formation via an N,O-acetal forged the 3-azabicyclo[3.3.1]nonane core. The allyl alc. moiety was constructed by a sequence involving stereoselective α-selenylation of an aldehyde via an enamine, syn-elimination of a selenoxide, and allylation of the aldehyde with an allylboronate. Formation of the 15-membered ring containing a skipped diene was achieved by ring-closing metathesis, and final transformations led to the synthesis of haliclonin A.

Higashi, Takuya;Kusumoto, Shuhei;Nozaki, Kyoko research published 《 Umpolung of B-H Bonds by Metal-Ligand Cooperation with Cyclopentadienone Iridium Complexes》, the research content is summarized as follows. In contrast to conventional metal-ligand cooperative cleavage of a B-H bond, which provides a B cation on the ligand and an H anion on the metal, we report herein the umpolung of B-H bonds by novel cyclopentadienone iridium complexes. The B-H bonds of 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (HBpin) and 1,8-naphthalenediaminatoborane (HBdan) were cleaved to give a B anion on the metal and an H cation on the phenolic oxygen atom of the ligand. Mechanistic investigation by DFT calculations revealed that the alkoxycarbonyl-substituted cyclopentadienone ligand facilitated deprotonation from Ir-H after oxidative addition of the B-H bond to give the umpolung product. The generated boryliridium complex was found to undergo borylation of an allyl halide in the presence of base, thus showing the nucleophilic nature of the boron atom.

Hoggard, Logan R.;Zhang, Yongqiang;Zhang, Min;Panic, Vanja;Wisniewski, John A.;Ji, Haitao research published 《 Rational Design of Selective Small-Molecule Inhibitors for β-Catenin/B-Cell Lymphoma 9 Protein-Protein Interactions》, the research content is summarized as follows. Selective inhibition of α-helix-mediated protein-protein interactions (PPIs) with small organic mols. provides great potential for the discovery of chem. probes and therapeutic agents. Protein Data Bank data mining using the HippDB database indicated that (1) the side chains of hydrophobic projecting hot spots at positions i, i + 3, and i + 7 of an α-helix had few orientations when interacting with the second protein and (2) the hot spot pockets of PPI complexes had different sizes, shapes, and chem. groups when interacting with the same hydrophobic projecting hot spots of α-helix. On the basis of these observations, a small organic mol., 4′-fluoro-N-phenyl-[1,1′-biphenyl]-3-carboxamide, was designed as a generic scaffold that itself directly mimics the binding mode of the side chains of hydrophobic projecting hot spots at positions i, i + 3, and i + 7 of an α-helix. Convenient decoration of this generic scaffold led to the selective disruption of α-helix-mediated PPIs. A series of small-mol. inhibitors, e.g. I, selective for β-catenin/B-cell lymphoma 9 (BCL9) over β-catenin/cadherin PPIs was designed and synthesized. The binding mode of new inhibitors was characterized by site-directed mutagenesis and structure-activity relationship studies. This new class of inhibitors can selectively disrupt β-catenin/BCL9 over β-catenin/cadherin PPIs, suppress the transactivation of canonical Wnt signaling, downregulate the expression of Wnt target genes, and inhibit the growth of Wnt/β-catenin-dependent cancer cells.

Copper-catalyzed oxidative cross-coupling of benzylic C-H bonds with alcs. to afford benzyl ethers, enabled by a redox buffering strategy that maintains the activity of the copper catalyst throughout the reaction was reported. The reactions employ the C-H substrate as the limiting reagent and exhibit broad scope with respect to both coupling partners. This approach to direct site-selective functionalization of C(sp³)-H bonds provides the basis for efficient three-dimensional diversification of organic mols. and should find widespread utility in organic synthesis, particularly for medicinal chem. applications.

Han, Songzhe;Zard, Samir Z. research published 《 A convergent route to substituted azetidines and to Boc-protected 4-aminomethylpyrroles》, the research content is summarized as follows. A radical addition of xanthates to BOC-protected azetine gives adducts, which can be reductively dexanthylated to furnish variously substituted azetidines. In the case of α-xanthyl ketones, treatment of the initial adducts with ammonia or primary amines, furnishes 2,4-disubstituted, 2,3,4-trisubstituted, and polycyclic pyrroles having a protected aminomethyl group at position-4. An unusual ring opening was observed in the case of a cyclobutanone precursor. It also proved possible to add an azetidinyl radical to an indole ring. Most of these products would be very difficult to obtain by more conventional routes. The synthesis of the target compounds was achieved by a reaction of 1(2H)-azetecarboxylic acid 1,1-dimethylethyl ester with xanthate derivatives, such as 2-[(ethoxythioxomethyl)thio]propanedioic acid ester, isoindole derivatives, a corticosteroid analog, etc.

Haut, Franz-Lucas;Habiger, Christoph;Wein, Lukas A.;Wurst, Klaus;Podewitz, Maren;Magauer, Thomas research published 《 Rapid Assembly of Tetrasubstituted Furans via Pummerer-Type Rearrangement》, the research content is summarized as follows. A powerful protocol to rapidly construct tetrasubstituted, orthogonally functionalized furans under mild reaction conditions was developed. The developed method involved the regioselective ring-opening of readily available 2,5-dihydrothiophenes followed by an oxidative cyclization to provide the heterocycle. The selective oxidation at sulfur is promoted by N-chlorosuccinimide as an inexpensive reagent and proceeds at ambient temperature in high yield within 30 min. The obtained furans serve as exceptionally versatile intermediates and were shown to participate in a series of valuable postmodifications. The fate of the initial sulfonium intermediate was investigated by mechanistic experiments, and computational studies revealed the existence of an unprecedented Pummerer-type rearrangement. The potential for organic synthesis is highlighted by the total synthesis of bisabolene sesquiterpenoids (pleurotins A, B, and D).
