ABSTRACT A novel, efficient total synthesis of a series of pterindithiolenes (15, 16, 17 and 18) [(5,6-dihydro-[1,4]dithiin or 6,7-dihydro-5H-[1,4]dithiepin systems respectively for six and seven membered dithiolenes] has been reported. The six membered quinoxaline thioketal 9 and seven membered quinoxaline dithiolene 11 have also been synthesized from quinoxaline acetylenic alcohol 5 and the corresponding
摘要 一系列蝶二硫烯 (15, 16, 17 和 18) [(5,6-dihydro-[1,4] dithiin or 6,7-dihydro-5H-[1,4] dithiepin) 的新型高效全合成分别为六元和七元二硫醇的系统]已经报道。六元喹喔啉硫缩酮 9 和七元喹喔啉二硫醇 11 也分别由喹喔啉炔醇 5 和相应的炔酮 10 合成。五元蝶呤硫缩酮的合成 12还报道了通过与 NBS 反应将 13 和 13 以及 13 转化为二硫烯 14。
