A metal‐free oxidative decarbonylative coupling of aliphaticaldehydes with various electron‐deficient heterocycles has been developed. This reaction is supposed to be realized via a Minisci‐type mechanism, based on the substrate scope, regioselectivity and radical trapping experiments. The ready availability of aliphaticaldehydes, metal‐free conditions and broad substrate scope should make this method
Synthesis of heteroaryl amines has been an important topic in organic chemistry because of their importance in small-molecule discovery. In particular, 2-aminopyrimidines represent a highlyprivilegedstructuralmotif that is prevalent in bioactive molecules, but a general strategy to introduce the pyrimidine C2–N bonds via direct functionalization is elusive. Here we describe a synthetic platform

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
