A rapid synthesis of chiral sulfoxide-functionalized meta-terphenyl derivatives by a 2,5-[C4+C2] ring transformation reaction of pyrylium salts with in situ generated enantiomerically pure α-sulfinylacetaldehydes is described in this paper. This synthetic method demonstrates, for the first time, the use of α-sulfinylacetaldehydes in a reaction sequence initiated by the nucleophilic attack of pyrylium
本文描述了通过吡喃鎓盐与原位生成的对映体纯的α-亚磺酰基乙醛的2,5-[C4+C2]环转化反应快速合成手性亚砜官能化间三联苯衍生物。该合成方法首次证明了在反应序列中使用α-亚磺酰乙醛,该反应序列由α-亚磺酰碳负离子对吡喃鎓盐的亲核攻击引发,以生成手性芳香族体系。该方法显示出广泛的适用性,从各种甲基亚砜和许多官能化吡喃鎓盐开始,从易于获得的起始化合物提供具有复杂取代模式的间三联苯。
