7-Alkyl- and 7-Cycloalkyl-5-aryl-pyrrolo[2,3-d]pyrimidines—potent inhibitors of the tyrosine kinase c-Src
摘要:
7-Substituted-5-aryl-pyrrolo[2,3-d]pyrimidines have been prepared starting from alpha -bromoacetophenones. These compounds represent a novel class of potent inhibitors of the tyrosine kinase pp60(c-Src) with good specificity towards other tyrosine kinases (EGF-R, v-Abl). (C) 2001 Elsevier Science Ltd.

There are described pyrrolo[2,3]pyrimidines of formula I ##STR1## wherein R.sub.1 -R.sub.5, m and n are as defined in the description. The compounds have valuable pharmaceutical properties and are effective especially as tyrosine protein kinase inhibitors. They can be used in the treatment of bone diseases and other diseases in warm-blooded animals that can be favorably influenced by the inhibition of tyrosine protein kinase.
general and highly efficient method for the synthesis of dl-2,3-diamide-1,4-diones via autoxidative dehydrogenative homocoupling of N-acyl-2-aminoacetophenones mediated by t-BuOK. The transformation is mild, operationally simple, and environmentally friendly. Control experiments and stereochemical results suggest that the substrate undergoes autoxidation followed by a diastereoselective SN2 reactopm.

Oxidative Cross-Coupling of α-Amino Ketones with Alcohols Enabled by I<sub>2</sub>-Catalyzed C–H Hydroxylation
oxidative cross-coupling of α-amino ketones with a wide range of alcohols is described. Using a combination of air and dimethyl sulfoxide (DMSO) as oxidants, the protocol allows an efficient synthesis of α-carbonyl N,O-acetals with high functional group tolerance and enables the late-stage introduction of α-amino ketones into biorelevant alcohols. Moreover, the present method can be used in the coupling of
