A facile method for the synthesis of 3-(aminomethylene)oxindoles from isatylidene malononitriles and α-azido ketones

Kamalraja, Jayabal,Babu, Thelagathoti Hari,Muralidharan, Doraiswamy,Perumal, Paramasivan Thirumalai

, p. 1950 - 1954 (2012)

A simple one-pot synthesis of 3-(aminomethylene)oxindoles was achieved by the reaction of α-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. Georg Thieme Verlag Stuttgart · New York.
