ABSTRACT The unnatural E isomer of anacardic acid 7 has been synthesized employing the following key steps: Swern oxidation of a diastereoisomeric mixture of β-hydroxyphosphine oxides 13a/b to the corresponding ketone 14 followed by stereospecific reduction to the pure threo isomer 13b which upon treatment with sodium hydride underwent trans elimination to afford the E ester 15.
摘要 漆树酸 7 的非天然 E 异构体的合成采用以下关键步骤:将 β-羟基氧化膦 13a/b 的非对映异构混合物的 Swern 氧化为相应的酮 14,然后立体有择地还原为纯苏式异构体 13b,在处理后与氢化钠进行反式消除,得到 E 酯 15。
