A dream come true: ABT‐341 was synthesized in high yield with excellent diastereo‐ and enantioselectivity in a one‐pot process mediated by a diphenylprolinol silyl ether (see scheme; TMS=trimethylsilyl). Thus, an asymmetric Michael reaction, a domino Michael/Horner–Wadsworth–Emmons reaction combined with a retro‐aldol reaction, base‐catalyzed isomerization, amide‐bond formation, and reduction of the
梦想成真:在由二苯基脯氨醇甲硅烷基醚介导的一锅法中,高收率合成ABT-341,具有出色的非对映异构和对映选择性(参见方案; TMS =三甲基甲硅烷基)。因此,一个不对称的迈克尔反应,一个多米诺骨牌迈克尔/霍纳-沃兹沃思-埃蒙斯反应与一个逆醛醇反应,碱催化的异构化反应,酰胺键的形成以及硝基的还原都在一个烧瓶中进行。
