Stereocontrolled synthesis of (−)-afzelechin was achieved via the Mitsunobu reaction, where complete stereospecificity was observed when an electron-withdrawing group was introduced to the para-position of the B-ring fragment.
通过 Mitsunobu 反应实现了 (-)-afzelechin 的立体定向合成,当在 B 环片段的对位引入一个抽电子基团时,可观察到完全的立体特异性。
