Reaction of chiral allylic and dienylic cyclic carbonates with various nucleophiles in the presence of (PPh3)4Pd as a catalyst afforded α-, γ-, or ε-substituted products with high regio-, (E)-stereo-, and diastereoselectivity depending on nucleophiles.
在催化剂存在下(PPh 3)4 Pd的存在下,手性烯丙基和二烯基环状碳酸酯与各种亲核试剂的反应生成具有高区域,(E)-立体和非对映选择性的α-,γ-或ε-取代产物取决于亲核试剂。
