synthesis of the (9R,13R)-stereoisomer of LDS1, a flower-inducing oxylipin isolated from Lemna paucicostata, has been achieved from a known allylic alcohol by a seven-step sequence that involves the Horner-Wadsworth-Emmons olefination to construct its full carbon framework and an enzymatic hydrolysis of a penultimate methyl ester intermediate to provide the target molecule.
LDS1的(9R,13R)-立体异构体是从Lemna paucicostata分离出的一种诱导花的脂环素的首次合成,是通过一种已知的烯丙基醇通过七步序列完成的,该过程涉及Horner-Wadsworth-Emmons烯化反应来构建其全碳骨架和倒数第二个甲酯中间体的酶促水解以提供目标分子。
