Functionalized electron-rich pyridines as initiators for the epoxy homopolymerization
, 2023 A simple and modular dialkylation of two electron-rich pyridine derivatives, namely 4-aminopyridine or 1,2,3,4-tetrahydropyrido[3,4-b]pyrazine, is achieved by aza-Michael reactions with electron-poor olefins (ethyl acrylate and acrylonitrile).
