Abstract
[reaction: see text] The "Southern Hemisphere" intermediate 2, used by Masamune and co-workers for their asymmetric total synthesis of bryostatin 7 (1), has been synthesized from (E)-1,4-hexadiene (11) by a 24-step pathway that has a longest linear sequence of only 20 steps. This is the shortest synthesis of 2 so far recorded, and moreover, it is fully stereocontrolled.
摘要
[反应：见正文] 正木及其同事用于不对称全合成苔藓抑素7（1）的“南半球”中间体2，已通过一条24步的路线从（E）-1,4-己二烯（11）合成，该路线最长线性序列仅20步。这是迄今为止记录的2的最短合成路线，而且它是完全立体控制的。
