An enantioselective insertion of a carbene into the Csp2–H bond of anisole derivatives has been accomplished using an achiral gold complex and a chiral phosphoric acid as the catalytic system, providing a novel protocol for the synthesis of chiral α,α-diaryl acetates. Density functional theory calculations reveal the reactivity and the origin of the enantioselectivity of this reaction.
使用非手性金配合物和手性磷酸作为催化体系,将卡宾选择性插入苯甲醚衍生物的 Csp 2 -H 键,为合成手性 α,α-二芳基乙酸酯提供了新的方案。密度泛函理论计算揭示了该反应的反应性和对映选择性的起源。
