Morpholine ketene aminal is employed in iridium-catalyzed asym. allylic alkylation reactions as a surrogate for amide enolates to prepare γ,δ-unsaturated β-substituted morpholine amides. Kinetic resolution or, alternatively, stereospecific substitution affords the corresponding products in high enantiomeric excess [e.g., (±)-I + II → (R)-III + (S)-I]. The utility of the products generated by this method has been showcased by their further elaboration into amines, ketones, or acyl silanes. A putative catalytic intermediate (η3-allyl)iridium(III) with achiral P,olefin-ligand was synthesized and characterized for the first time.

Although many compounds look similar to this compound(1265884-98-7)Electric Literature of C34H22NO2P, numerous studies have shown that this compound(SMILES:N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81), has unique advantages.

Quality Control of H-Trp-OMe.HCl. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: H-Trp-OMe.HCl, is researched, Molecular C12H15ClN2O2, CAS is 7524-52-9, about A new class of α-ketoamide derivatives with potent anticancer and anti-SARS-CoV-2 activities.

Inhibitors of the proteasome have been extensively studied for their applications in the treatment of human diseases such as hematol. malignancies, autoimmune disorders, and viral infections. Many of the proteasome inhibitors reported in the literature target the non-primed site of proteasome′s substrate binding pocket. In this study, we designed, synthesized and characterized a series of novel α-keto phenylamide derivatives aimed at both the primed and non-primed sites of the proteasome. In these derivatives, different substituted Ph groups at the head group targeting the primed site were incorporated in order to investigate their structure-activity relationship and optimize the potency of α-keto phenylamides. In addition, the biol. effects of modifications at the cap moiety, P1, P2 and P3 side chain positions were explored. Many derivatives displayed highly potent biol. activities in proteasome inhibition and anticancer activity against a panel of six cancer cell lines, which were further rationalized by mol. modeling analyses. Furthermore, a representative α-ketoamide derivative was tested and found to be active in inhibiting the cellular infection of SARS-CoV-2 which causes the COVID-19 pandemic. These results demonstrate that this new class of α-ketoamide derivatives are potent anticancer agents and provide exptl. evidence of the anti-SARS-CoV-2 effect by one of them, thus suggesting a possible new lead to develop antiviral therapeutics for COVID-19.

In the presence of [Ir(cod)Cl]2 and a nonracemic dibenzazepinyl dinaphthodioxaphosphepine ligand, hydroxy ketone-containing allylic carbonates such as I (Boc = t-BuO2C) underwent distereoselective and enantioselective spiroketalization reactions to yield spiroketals such as II in 62-99% yields, 1.2:1->25:1 dr (the diastereoselectivity of the 1.2:1 dr reaction was improved to >25:1 dr on equilibration with acid), and in 94:6->99:1 er. The protocol was effective for the preparation of a collection of spiroketals of various ring sizes and substituents, including heteroatoms, with high enantio- and diastereoselectivity. Furthermore, the enantio- and diastereoselective spiroketalization was used in tandem with an acetalization reaction and a second spiroketalization reaction to exert concomitant stereocontrol over addnl. stereogenic centers. The structure of a nonracemic spiropyranpyrrolopyran was determined by X-ray crystallog.
