Convenient Direct Synthesis of Vinylogous Urea Derivatives Using Magnesium Amide-induced Amide/Nitrile Coupling
摘要:
The magnesium enolates, generated by treatment of acyclic (1) and cyclic tertiary amides (4) with a (diisopropylamino)magnesium reagent, reacted efficiently with nitriles (2) to afford the corresponding beta-aminoacrylamides (3) and alpha-(alpha-aminoalkylidene)lactams (5). The formation of alpha-(2-pyrrolidinylidene)lactams (7) from the reactions of N-methyl-2-pyrrolidone and N-methyl-2-piperidone with a gamma-cyanopropyl p-toluenesulfonate (6) is also described.
