A one‐step enantioselective directsynthesis of both syn‐ and anti‐α,β‐dihydroxy γ‐keto esters using a dinuclear zinc–AzePhenol complex is presented. This asymmetric α‐hydroxyacetate aldolreaction proceeds in moderate to good yield and with excellent enantioselectivity of up to 99 % ee. The desired products could be used as versatile intermediates for several transformations.

A new dinuclear zinc cooperative catalytic enantioselective three-component reaction via a domino Knoevenagel /Michael/cyclization sequence has been developed. A series of chiral 3,3'-dihydrofuran spirooxindoles are obtained in excellent yields (up to 99%) and enantioselectivities (up to 99% ee). In addition, the reaction is carried out smoothly on a gram scale under mild conditions.
通过多米诺Knoevenagel / Michael /环化序列开发了一种新的双核锌协同催化对映选择性三组分反应。获得了一系列手性的3,3'-二氢呋喃螺硫醇,具有优异的收率(高达99%)和对映体选择性(高达99%ee)。另外,该反应在温和条件下以克为单位平稳地进行。
