A practical stereoselective synthesis of (S)-bakuchiol (1) and its enantiomer is reported. The important intermediate, (R)-configured β-siloxy aldehyde 5, was obtained in three steps from the easily available material geraniol (2) via the key step of Yamamoto's rearrangement of epoxy silyl ethers. (S)-Bakuchiol (1) and its enantiomer, (R)-bakuchiol (17), were finally obtained in different synthetic
报道了一种实用的立体选择性合成(S)-幕果酚(1)及其对映异构体。通过山本重整环氧甲硅烷基醚的关键步骤,从容易获得的原料香叶醇(2)分三步获得了重要的中间体(R)构型的β-甲硅烷基醛5。最终以不同的合成顺序获得了香叶醇(2)的(S)-幕府酚(1)及其对映异构体(R)-幕府酚(17),总产率为51%(十步)和40%(九步)。, 分别。
