CC coupling: DiPPAM 1 and BINAP 2 ligands led to divergent behaviors in the asymmetric conjugate addition (ACA) of dialkylzinc reagents to linear aryldienones, which were applied to the development of a highly selective sequential asymmetric 1,6/1,4-ACA process (see scheme; Tf = triflate, DBU = 1,8-diazabicyclo[5.4.0]undec-7-ene).
CC 偶联:当使用 DiPPAM(1)和 BINAP(2)配体时,在二烷基锌试剂对线性芳二烯酮的不对称共轭加成(ACA)中表现出不同的行为,这一现象被应用于高选择性的连续不对称 1,6/1,4-ACA 过程的发展(见方案;Tf=三氟甲磺酸酯,DBU=1,8-二氮杂二环[5.4.0]十一-7-烯)。
