本文描述了支化外消旋烯丙基醇与丙二酸酯的对映选择性烷基化反应。在carira的手性Ir/(P,烯烃)配合物的作用下,该方法允许烯丙基取代各种芳香醇和丙二酸酯,具有优异的对映选择性。丙二酸酯可以直接作为高效的亲核试剂而不需要预活化。
Ir-catalyzed enantioselective allylic alkylation of branched racemic allylic alcohols with malonates is described. Enabled by Carreira's chiral Ir/(P, olefin) complex, the method described allows allylic substitution with various aromatic alcohols and malonates with excellent enantioselectivity. The malonates could be used directly as efficient nucleophiles without the need of preactivation.
