A novel asymmetric [4+1] annulation of MBH carbonates with dicyano-2-methylenebut-3-enoates has been developed for the first time, providing an efficient and enantioselective synthesis of highly functionalized cyclopentenes bearing one all-carbon quaternary stereogenic center.
首次发展了 MBH 碳酸盐与二氰基-2-亚甲基丁-3-烯酸酯的新型不对称 [4+1] 环化反应,为具有一个全碳季立体中心的高官能化环戊烯提供了高效和对映选择性的合成方法。
