reason for which remains to be elucidated. The first enantioselective total syntheses of two marine sesquiterpenes, natural (1S)-suberosanone and (1S)-suberosenol A, are achieved leading to the assignment of the absolute configuration of natural suberosenol A. A new access to (1S)-suberosenone from a key tricyclic enone was also developed leading to an overall improvement of the synthesis, allowing an
献给已故的让·安杰洛教授 抽象 实现了两个海洋倍半萜的第一个对映选择性全合成,天然(1 S)-suberosanone和(1 S)-suberosenol A,导致确定了天然Suberosenol A的绝对构型。获得了(1 S)-还开发了关键三环烯酮的亚硝基苯甲酸酯,从而导致合成的整体改进,从而为亚硝基苯甲酚A提供了有效的途径。高压不对称迈克尔加成反应和高效的三氟乙酸银介导的α-烷基化以形成环A完成了关键步骤的合成。遗憾的是,合成(1 S)-异戊烷酮未保留天然产物所显示的皮摩尔细胞毒性活性,其原因尚待阐明。 实现了两个海洋倍半萜的第一个对映选择性全合成,天然(1 S)-suberosanone和(1 S)-suberosenol A,导致确定了天然Suberosenol A的绝对构型。获得了(1 S)-还开发了关键三环烯酮的亚硝基苯甲酸酯,从而导致合成的整体改进,从而为亚硝基苯甲酚A提供了
