α-aminophosphonates and imines on the basis of citral, citronellal, and (-)-myrtenal

摘要

The Kabachnik-Fields reaction of citral with dialkyl phosphites in the presence alkyl amines; the imine formation reaction of E,Z-citral, R,S-citronellal, and (R)-(-)-myrtenal with primary amines; and Pudovik reactions of prenyl imines obtained with dialkyl phosphites or with O,O-dialkyl trimethylsilylphosphites were studied. On the basis of these studies, new unsaturated prenyl imines and α-aminophosphonates were prepared.
