On the basis of Zhou’s modified Sharpless asymmetric epoxidation, sequential coupling reactions, and a divergent strategy, the protection-free syntheses of two main pheromonal components 1 and 5, found in the fall webworm moth, Hyphantria cunea, and other species have been accomplished in 10 steps (for two compounds). The overall yields are 31% for 1, 28% for 5, and 25% for both 1 and 5, respectively
根据周氏改良的Sharpless不对称环氧化,顺序偶联反应和发散策略,在秋季的网虫蛾,Hyphantria cunea和其他物种中发现的两个主要信息素组分1和5的无保护合成已经完成。 10个步骤(用于两种化合物)。总体产率31%1,28%5,和两个25%1和5,分别。最终产品1和5的ee值至少为99%。
