The first diastereoselective synthesis of the antimicrobial and cytotoxic agent (–)-caulerpenynol (2) was achieved in relatively few steps from commercially available (S)-malic acid. Highlights of this synthesis include the nonracemization of the sensitive α-hydroxy ketone moiety and the proper choice of the protecting groups for critical last deprotection step.

抗菌剂和细胞毒性剂 (-)-caulerpenynol (2) 的第一个非对映选择性合成是通过相对较少的步骤从市售的 (S)-苹果酸中实现的。该合成的亮点包括敏感的 α-羟基酮部分的非外消旋化以及为关键的最后去保护步骤正确选择保护基团。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
