Asymmetric alkylation of 2,3-alkadienyl phosphates with soft carbon nucleophiles proceeds efficiently in the presence of palladium complex catalyst bearing MeOBIPHEP or BINAP ligand to give optically active functionalized allenes up to 90% ee.
在带有 MeOBIPHEP 或 BINAP 配体的钯配合物催化剂存在下,2,3-链二烯基磷酸酯与软碳亲核试剂的不对称烷基化可有效进行,得到高达 90% ee 的旋光功能化丙二烯。
