describe the synthesis of key intermediate (+)-8 as an essential intermediate including full carbon framework for completing the convergent total synthesis of Actinoallolide A (1). (+)-8 was obtained by Negishi and Stille cross coupling from (+)-9, (+)-10 and (−)-11. Stereo-divergent preparation of two similar units, consisting of three consecutive stereocenters, facilitated the synthesis of (+)-10 and
在这里,我们描述了关键中间体(+)- 8的合成,该化合物是必不可少的中间体,其中包括完整的碳骨架,以完成放线肌醇A(1)的会聚全合成。(+)- 8是通过Negishi和Stille交叉耦合从(+)- 9,(+)- 10和(-)- 11获得的。由三个连续的立体中心组成的两个相似单元的立体发散制备,促进了(+)- 10和(-)- 11的合成。
