Abstract

An efficient synthetic protocol for 2-(1-aryl-2-nitroethyl)-3-arylaminoacrylates was successfully developed by the one-pot domino reaction of arylamines, methyl propiolate, and nitrostyrenes. The reaction involves the formation of β-enamino ester and its sequential Michael addition to nitrostyrene.
