A stereoselective total synthesis of (−)-cleistenolide (1) derived from d-(−)-isoascorbic acid has been described. The new synthetic strategy involves highly diastereoselective reduction, one-pot protection of required benzoyl, acetyl groups, and the RCM reaction by using Grubbs catalyst are the key steps with considerable yields.
已经描述了衍生自d -(-)-异抗坏血酸的(-)-苦杏仁苷(1)的立体选择性全合成。新的合成策略涉及高度非对映选择性还原,一锅保护所需的苯甲酰基,乙酰基,以及通过使用Grubbs催化剂进行RCM反应是获得可观收率的关键步骤。
