A route enabling the synthesis of the stereo-triad of rishirilide B (1) from 2-hydroxy-3-methylnaphthalene-1,4-dione, is reported. Key transformations include the regioselective 1,2-Grignard addition to a tautomeric mixture of o- and p-quinones, regioselective carbamoylation of a tautomeric mixture, and a synopsis of the methods explored to convert various terminal vinyl ethers into the corresponding carboxylic acid by cleavage.
报道了一种从 2-羟基-3-甲基萘-1,4-二酮合成立体三联体 rishirilide B (1) 的路线。关键转化包括邻醌和对醌互变混合物中的区域选择性 1,2-格氏加成、互变混合物的区域选择性氨基甲酰化,以及通过裂解将各种末端乙烯基醚转化为相应羧酸的方法概要。
