The pairing of unstabilized nitrogen ylides generated in situ with functionalized thiolesters under ambient conditions resulted in a new intramolecular carbon–carbon bond forming reaction. The scope of the reaction was illustrated with a series of substituted thiolester substrates. This reaction represents a new method for the synthesis of 2-substituted tetrahydrothienyl compounds through a unique
在环境条件下原位生成的不稳定氮叶立德与官能化硫醇酯的配对导致新的分子内碳-碳键形成反应。反应范围用一系列取代的硫醇酯底物说明。该反应代表了一种通过独特的 1,2-硫醇转移合成 2-取代四氢噻吩基化合物的新方法。虽然氮叶立德以前已用于合成,但很少有将不稳定的氮叶立德用于具有合成意义的转化的例子。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
