报道了手性二胺催化的α,β-不饱和酮酯与无环酮的高效不对称羟醛缩合反应。以优异的产率和优异的对映选择性获得了相应的产物。通过X射线分析确定产物的绝对构型。本催化体系可耐受多种底物。
Highly efficient asymmetric aldol reactions between α,β-unsaturated keto esters and acyclic ketones catalyzed by chiral diamines are reported. The corresponding products were obtained in excellent yields with excellent enantioselectivities. The absolute configuration for the product was determined by X-ray analysis. A variety of substrates were tolerable in the present catalytic system.
