SYNTHESIS OF 1-ALKYL-2-ARYLPYRROLES FROM ARYL(3-BROMO-2-METHOXYPROPYL)KETONES
Sorokin, V. L.,Azzuz, A. A.,Kulinovich, O. G.
, p. 271 - 272 (2007/10/02)
Aryl(3-bromo-2-methoxypropyl)ketones have been obtained by bromination of allylarylketones using N-bromosuccinimide.When treated with primary amines, good yields of 1-alkyl-2-arylpyrroles were obtained via 1,3-dehydrobromination and subsequent opening of
