Product Details of 1195-59-1In 2021 ,《Azine-N-oxides as effective controlling groups for Rh-catalyzed intermolecular alkyne hydroacylation》 was published in Chemical Science. The article was written by Moseley, Daniel F.; Kalepu, Jagadeesh; Willis, Michael C.. The article contains the following contents:

Azine N-oxide substituted aldehydes are used as highly effective substrates with good reactivity for intermol. hydroacylation of alkynes. Employing a Rh(I)-catalyst, a mild and scalable aldehyde C-H activation, that permits the coupling with unactivated terminal alkynes was achieved in good yields and with high regioselectivities (up to >20 : 1 l:b). Both substrates can tolerate a broad variety of functional groups. The reaction can also be applied to diazine aldehydes that contain a free N-lone pair. Conversion of the hydroacylation products to the corresponding azine, through a one-pot hydroacylation/deoxygenation sequence was also demonstrated. A one-pot hydroacylation/cyclization, using N-Boc propargylamine, addnl. leads to the synthesis of a bidentate pyrrolyl ligand. In the part of experimental materials, we found many familiar compounds, such as 2,6-Pyridinedimethanol(cas: 1195-59-1Product Details of 1195-59-1)

The article was 《Potent noncovalent inhibitors of the main protease of SARS-CoV-2 from molecular sculpting of the drug perampanel guided by free energy perturbation calculations》. The article mentions the following:

Starting from our previous finding of 14 known drugs as inhibitors of the main protease (Mpro) of SARS-CoV-2, the virus responsible for COVID-19, we have redesigned the weak hit perampanel to yield multiple noncovalent, nonpeptidic inhibitors with ca. 20 nM IC50 values in a kinetic assay. Free-energy perturbation (FEP) calculations for Mpro-ligand complexes provided valuable guidance on beneficial modifications that rapidly delivered the potent analogs. The design efforts were confirmed and augmented by determination of high-resolution X-ray crystal structures for five analogs bound to Mpro. Results of cell-based antiviral assays further demonstrated the potential of the compounds for treatment of COVID-19. In addition to the possible therapeutic significance, the work clearly demonstrates the power of computational chem. for drug discovery, especially FEP-guided lead optimization.

Application In Synthesis of (R)-Oxiran-2-ylmethanolOn March 19, 2021, Bold, Christian P.; Klaus, Cindy; Pfeiffer, Bernhard; Schurmann, Jasmine; Lombardi, Rafael; Lucena-Agell, Daniel; Diaz, J. Fernando; Altmann, Karl-Heinz published an article in Organic Letters. The article was 《Studies toward the Synthesis of an Oxazole-Based Analog of (-)-Zampanolide》. The article mentions the following:

Studies are described toward the synthesis of an oxazole-based analog I of (-)-zampanolide. Construction of (-)-dactylolide analog 22 was achieved via alc. II and acid III through esterification and Horner-Wadsworth-Emmons (HWE)-based macrocyclization; however, attempts to attach (Z,E)-sorbamide to I proved unsuccessful. The C(8)-C(9) double bond of the macrocycle was prone to migration into conjugation with the oxazole ring, which may generally limit the usefulness of zampanolide analogs with aromatic moieties as tetrahydropyran replacements. The experimental process involved the reaction of (R)-Oxiran-2-ylmethanol(cas: 57044-25-4Application In Synthesis of (R)-Oxiran-2-ylmethanol)
