[reaction: see text] The first asymmetric palladium-catalyzed conjugate addition of arylboronic acids to alpha,beta-unsaturated aldehydes, ketones, and esters is described. For cyclic substrates, excellent chemo-, regio-, and enantioselectivities are achieved when a Pd(O2CCF3)2/DuPHOS catalyst is applied.
[反应:见正文]描述了芳基硼酸向α,β-不饱和醛,酮和酯的第一次不对称钯催化的共轭加成。对于环状底物,当使用Pd(O2CCF3)2 / DuPHOS催化剂时,可获得出色的化学选择性,区域选择性和对映选择性。
