Substituted 5,7-diphenyl-pyrrolo[2,3 d ]pyrimidines: potent inhibitors of the tyrosine kinase c-Src
摘要:
5,7-Diphenyl-pyrrolol[2,3d]pyrimidines represent a new class of highly potent inhibitors of the tyrosine kinase c-Src (IC50 < 50 nM) with specificity against a panel of different tyrosine kinases. The substitution pattern on the two phenyl rings determines potency and specificity and provides a means to modulate cellular activity. (C) 2000 Elsevier Science Ltd. All rights reserved.
for the simple copper‐catalyzedα‐amination of α‐aminocarbonyl compounds to afford 2‐amino‐2‐iminocarbonyl and 2‐amino‐2‐oxocarbonyl compounds is reported. This transformation is achieved by C(sp3)−H and N−H bond oxidative cross‐coupling and selective C−N bond oxidative cleavage. This reaction system has a broad reaction scope, providing a facile pathway for the α‐functionalization of α‐amino ketones
A one-pot oxidative cross-dehydrogenative [2 + 3] annulation of α-amino ketones with α-keto esters at room temperature is reported. The protocol features copper/organo cooperative catalysis and provides densely functionalized pyrrolones in high yields. Subsequent reduction furnished multi-substituted pyrrolidinones which represent the core-structure of the natural product clausenamide, a lead molecule

Regioselective Synthesis of 2-Arylindoles via Palladium-Catalyzed Cyclization of Phenylglyoxal and 2-Anilinoacetophenones with Anilines
A palladium‐catalyzed tandem reaction for synthesis of 2‐arylindoles is described. The process involves a condensation/reduction/condensation/heteroannulation to give the respective indole. Furthermore, it also features satisfactory yields and selectivities.
