The first examples of direct synthesis of γ-thiolactones by addition of a thiolactone-based radical are described. Mono- and bis-γ-thiolactones can be obtained by a dilauroyl peroxide initiated addition of thiolactone xanthate to various alkenes and α,ω-dienes. The process is modular and exhibits a high functional group tolerance.

基于黄原酸盐的直接制备 γ-硫内酯的途径

描述了通过添加基于硫内酯的自由基直接合成 γ-硫内酯的第一个例子。单-和双-γ-硫内酯可以通过过氧化二月桂酰引发的硫内酯黄原酸酯加成到各种烯烃和α，ω-二烯中获得。该过程是模块化的，表现出高官能团耐受性。
