Concise total syntheses of smenothiazoles A (1) and B (2), two distinguished vinyl chloride containing natural products isolated from the marine sponge S. aurea, have been developed. Silastannation, Stille reaction and a carefully controlled desilylchlorination were employed as key steps to construct unique polyketide acid fragments, and the optimized reaction conditions avoided migration of 2,5-diene
简明的总合成smenothiazoles A(1)和B(2),即从海洋海绵金黄色葡萄球菌中分离得到的两种不同的含氯乙烯的天然产物。甲硅烷基化,斯蒂勒反应和精心控制的脱甲硅烷基氯反应被用作构建独特的聚酮酸片段的关键步骤,并且优化的反应条件避免了2,5-二烯向2,4-共轭体系的迁移。该报告明确证实了两种天然产物的结构。
