phosphine ligands, a Pd-catalyzed asymmetric double hydroxycarbonylation of terminal alkynes to chiral succinic acids was achieved in a one-pot manner. The alkyne carbonylation was dictated by the achiral monophosphine to afford branched acrylic acids, while the resulting intermediates further underwent Pd/chiral bisphosphine-catalyzed enantioselective hydroxycarbonylation.
通过结合两种不同的膦配体,以一锅法实现了末端炔烃到手性琥珀酸的 Pd 催化不对称双羟基羰基化反应。炔烃羰基化由非手性单膦决定,以提供支链丙烯酸,而所得中间体进一步经历 Pd/手性双膦催化的对映选择性羟基羰基化。
