A Facile Method for the Synthesis of 3-(Aminomethylene)oxindoles from Isatylidene Malononitriles and α-Azido Ketones
摘要:
A simple one-pot synthesis of 3-(aminomethylene)oxindoles was achieved by the reaction of alpha-azido ketones and isatylidene malononitriles via Michael addition followed by the conversion of azides to amines. All the synthesized 3-(aminomethylene)oxindoles exhibited good diastereoselectivity.
