Imines of glycine methyl esters, o-propargyloxybenzylidene(methoxycarbonyl)methylamines, undergo an intramolecular cycloaddition via their 1,3-dipolar tautomers, azomethine ylides, to an alkynyl group. Initial cycloadducts were thermally converted to dehydrogenated compounds with concurrent migration of methoxycarbonyl group.
