A new, highly efficient, selective methodology for formation of medium-ring and macrocyclic lactones via intramolecular ketene trapping: an application to a convergent synthesis of (-)-kromycin
An efficient stereoselective total synthesis of Diplodialide A has been achieved from inexpensive and commercially available starting material (R)-propylene oxide. This linear synthesis utilizes Wittig reaction, alkylation of 1,3-dithiane and Yamaguchi macrolactonization as key steps.
Diplodialide A 的高效立体选择性全合成已由廉价且可商购的起始材料 (R)-环氧丙烷实现。这种线性合成利用 Wittig 反应、1,3-二噻烷的烷基化和 Yamaguchi 大环内酯化作为关键步骤。
