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.
A general and mild method for the construction of a carbon–nitrogen bond via copper-catalyzedoxidativecross-coupling of amines with α-aminocarbonyl compounds was achieved. Amines, either aliphatic primary amines, aromatic primary amines or secondary amines can be used as the starting materials. When R2 was different from R3, two isomers would be observed. Therefore, this reaction system has a broad
ABSTRACT A novel iron-catalyzed oxidative coupling of indoles with α-amino carbonyl compounds has been developed. The transformation provides an attractive approach to the synthesis of 3-acylindoles, with the advantages of easily available starting materials and high functional group tolerance. Furthermore, control experiments imply that a radical process maybe involved in this reaction. GRAPHICAL
