Condensation of methyl phenyl(alkyl)halopyrotartrates with N, N'-diphenylselenourea leads to the formation of methyl 4-hydroxy-3-phenyl-5- phenyl(alkyl)-2-phenyliminoselenazolidine-4-carboxylates, which undergo reaction with 1,2-phenylenediamines to give selenazolo-[3,4-a]quinoxalin-4(5H)-ones. ; 2009 Springer Science+Business Media, Inc.
