Laurencin was efficiently synthesized from a C-glycoside derivative based on ring expansion of the oxane part of the starting compound into an eight-membered cyclic ether via a ring-cleavage/ring-closing olefin metathesis process, stereoselective introduction of a bromo group at C4, and convergent construction of the side-chain part using a lithiated enyne unit.
基于起始化合物的恶烷部分经开环/闭环烯烃复分解过程,在C4处有选择地引入溴基的立体选择,由C-糖苷衍生物有效合成Laurencin 。 ,并使用锂化的烯炔单元聚合构建侧链部分。
