A convenient synthesis and cytotoxic evaluation of N-unsubstituted α-methylene-γ-lactams
摘要:
Chemoselective reduction of 3-aryl-2-diethoxyphosphoryl-4-nitroalkanoates provided the corresponding alpha-diethoxyphosphoryl-gamma-lactams in completely diastereoselective manner. The products were shown to be useful substrates for the synthesis of mono-beta-substituted and beta,gamma-disubstituted alpha-methylene-gamma-lactams. Cytotoxicity of these compounds was evaluated.
