A new general method for 3,4-substituted and annelated thiophenes through intramolecular cyclocondensation of a sulphonium ylid intermediate under Simmons-Smith reaction conditions on α-oxoketene dithioacetals has been reported.
据报道,在Simmons-Smith反应条件下,在α-氧杂环丁烯二硫缩醛上进行intra基中间体的分子内环缩合,可以得到3,4-取代和噻吩基化的新方法。
