A Multicomponent Reaction for the One-Pot Synthesis of 4-Aza-2,3-didehydropodophyllotoxin and Derivatives
摘要:
A convergent method has been found to prepare 4-aza-2,3-didehydropodophyllotoxin and derivatives in a one-pot procedure. The mechanism of the reaction between tetronic acid, anilines, and benzaldehydes is discussed.
