The reaction of methyl azido(phenylhydrazono)acetate (1) with the enamines (4)-(7) leads to different kinds of ring-closed products, namely 1,2,4-triazines (8)-(10), 1,2,3-triazoles (12)-(15), and 1,2,4-triazoles (16)-(19).An open-chain azo compound (20) is also formed.In one case, an intermediate 4,5-dihydro-1H-1,2,3-triazole (11) has been isolated.A mechanistic picture is proposed involving preliminary cycloaddition of the azido group to the enamine and subsequent reaction of the 4,5-dihydro-1H-1,2,3-triazoles according to various concurrent pathways.
