Two-step or three-step one-carbon ring enlargement of lactones is realized from lactones and chloromethyl phenyl sulfoxide via a rearrangement of alkylidene carbenoid followed by intramolecular cyclization of the ω-hydroxyalkyl ketene intermediate or via a 2-pyridinethiol ester.
由内酯和氯甲基苯基亚砜通过亚烷基类胡萝卜素的重排,然后ω-羟烷基烯酮中间体的分子内环化或通过2-吡啶硫醇酯,实现内酯的两步或三步碳环扩大。
