The synthesis of imidazo[4',5':5,6]cycloocta[1,2-<i>B</i>]quinoxaline-2-ones and a – thione

Abstract

At present study, we synthesized the imidazo[4^',5^':5,6]cycloocta[1,2-b]quinoxaline-2-ones (-2-thione) with an additional double bond in the eight-membered ring via the reaction of a quinoxaline-fused cyclooctane-1,2-dione with urea (or thiourea) and N,N'-dimethylurea.

KEY WORDS: Quinoxaline, Imidazolone, Thioimidazolone, Cyclooctane-1,2-dione
