An efficient synthesis of (–)-(R)- and (+)-(S)-lavandulol, (+)-lavandulyl 2-methylbutanoate and (+)-lavandulyl senecioate is presented in this paper. The synthetic strategy features a chiral-pool approach to an allyl alcohol intermediate, and an orthoester Johnson–Claisen rearrangement as the key step.
本文介绍了 (-)-(R)- 和 (+)-(S)-lavandulol、(+)-lavandulyl 2-methylbutanoate 和 (+)-lavandulyl senecioate 的有效合成。合成策略的特点是对烯丙醇中间体采用手性池方法,并将原酸酯 Johnson-Claisen 重排作为关键步骤。
