A procedure was developed for the synthesis of 2-substituted, including 2-alkenyl-substituted, 4H-anthra[1,2-b]thiopyran-4,7,12-triones and 4H-anthra[2,3-b]thiopyran-4,6,11-triones by cyclocondensation of vic-alkynoylchloroanthraquinones with Na2S.
开发了一种通过与Na2S的环缩合反应合成2-取代的(包括2-烯丙基取代的)4H-蒽[1,2-b]噁噻吡喃-4,7,12-三酮和4H-蒽[2,3-b]噁噻吡喃-4,6,11-三酮的程序,该反应以vic-炔基氯蒽醌为起始物进行。
