Various 2-substituted 1,3-dioxolanes, 1,3-dioxanes, and tetrahydrofurans were obtained selectively in good to moderate yields from the corresponding alcohols with PSDIB in the presence of iodine under irradiation conditions. Moreover, PSDIB was repeatedly used for the same reactions keeping good yield of the cyclic product.
各种 2-取代的 1,3-二氧戊环、1,3-二氧六环和四氢呋喃在碘的存在下在辐照条件下从相应的醇与 PSDIB 中选择性地以良好到中等的产率获得。此外,PSDIB 被重复用于相同的反应,以保持环状产物的良好收率。
