for the synthesis of various sulfur-tethered vinylogous carbonates in good to excellent yields. Important features of the developed reaction include wide functional group tolerance, excellent chemo- and regioselectivity, and efficient rearrangement involving the carbonyl motif. The present reaction also equally works well with α-selenoesters for the synthesis of seleno-containing vinylogous carbonates
已经完成了由 α-硫酯/酮和重氮羰基化合物衍生的硫叶立德的高效铑催化空前的氧杂-[2,3]-σ 重排,用于以良好至优异的产率合成各种硫束缚的乙烯基碳酸酯。该反应的重要特征包括广泛的官能团耐受性、优异的化学和区域选择性以及涉及羰基基序的有效重排。本反应同样适用于用于合成含硒乙烯基碳酸酯的 α-硒酸酯。
