Abstract

Rearrangement of the Adducts of α-(Aminocarbonyl)acetamidoximes with Acylacetylenes, Leading to 2-Aminopyrrole Derivatives. -O-Vinylamidoximes [cf. (III)], obtained by addition of amidoximes (I) to acetylenes, rearrange spontaneously or thermally to furnish 2-acylaminopyrroles. -(PIVNEVA, E. E.; GALENKO, A. V.; DAR'IN, D. V.; LOBANOV*, P.
