[EN] SUBSTITUTED PYRAZOLO[1,5-A]PYRIMIDINE-7-AMINE COMPOUNDS AS CDK INHIBITORS AND THEIR THERAPEUTIC USE [FR] COMPOSÉS DE PYRAZOLO[1,5-A]PYRIMIDINE-7-AMINE SUBSTITUÉS EN TANT QU'INHIBITEURS DE CDK ET LEUR UTILISATION THÉRAPEUTIQUE
A highly enantioselective method for the complete hydrogenation of pyrimidinium salts using Ir/(S,S)-f-Binaphane complex as the catalyst was presented in this study. This approach affords facile access to a range of fully saturated chiral hexahydropyrimidines, which are prevalent in many bioactive molecules. The reactions showcase high yields and enantioselectivities under mild reaction conditions
