Glotova, T. E.,Nakhmanovich, A. S.,Skvortsova, G. G.,Komarova, T. N.,Kalikhman, I. D.,Voronkov, M. G.

, p. 653 - 658 (2007/10/02)

Bis(acylvinylaminoethyl) disulfides were synthesized by the reaction of α-acetylenic ketones with β-mercaptoethylamine in alcohol in the presence of sodium methoxide or in chloroform in the presence of potassium carbonate. 1,4-Bis(acylvinyl)-1-thia-4-azabutanes were obtained in the same way for acetylenic ketones with an aryl radical at the triple bond.
