obtained through the asymmetric catalytic cascade reaction between 3-amino-2-butenoates and (Z)-2-arylidene-3-oxobutanoates. The N,N′-dioxide/NiII or NdIII complex catalysts were disclosed to be efficient, furnishing a variety of the products, including drugs like nitrendipine, nimodipine, and felodipine, in high yields (up to 99% yield) with excellent enantioselectivities (up to 99% ee). Two enantiomers
通过 3-amino-2-butenoates 和 ( Z )-2-arylidene-3-oxobutanoates 之间的不对称催化级联反应,获得了带有不同酯基的光学富集的 Hantzsch 二氢吡啶。N ,N'-二氧化物/Ni II或 Nd III络合物催化剂据称是高效的,以高产率(高达 99% 的产率)和优异的性能提供多种产品,包括尼群地平、尼莫地平和非洛地平等药物对映选择性(高达 99% ee)。通过两种反应物酯基的交换,很容易得到产物的两种对映异构体。此外,还通过氧化过程提供了轴向手性 4-芳基吡啶。
