A range of 2,4-dialkylidenetropinone-derived quaternary ammonium salts smoothly reacted with thiols in the presence of tributylamine, delivering structurally diverse thiolated 2,7-disubstituted tropones in moderate to excellent yields with high site selectivity. The reaction employs readily available feedstocks and reagents, is free of transition metals, tolerates various functional groups, and can
一系列 2,4-二亚烷基托品酮衍生的季铵盐在三丁胺存在下与硫醇顺利反应,以中等至优异的收率和高位点选择性提供结构多样的硫醇化 2,7-二取代托品酮。该反应采用现成的原料和试剂,不含过渡金属,可耐受各种官能团,并且可以轻松扩大规模。
