reagents, and is atom economical, since both sulfur atoms of the xanthate end up in the products. With adducts derived from xanthates bearing an ester group, an unexpected transformation leading to lactones was uncovered.
描述了一种基于将黄原酸盐自由基加成到
烯丙基乙酸酯的 1,3-dithiolan-2-ones 的收敛路线。该过程是模块化的,使用廉价的起始材料和试剂,并且是原子经济的,因为黄原酸盐的两个
硫原子最终都会出现在产品中。对于衍生自带有酯基的黄原酸盐的加合物,发现了导致内酯的意外转化。
