在二甲基亚砜（DMSO）中的分子筛（MS）4A存在下，各种N-甲苯磺酰亚胺与活性亚甲基化合物的高度立体选择性Knoevenagel反应顺利进行，以高至优异的产率生成相应的Knoevenagel产物。
In the presence of molecular sieves (MS) 4A in dimethyl sulfoxide (DMSO), a highly stereoselective Knoevenagel reaction of various N-tosylimines with active methylene compounds proceeded smoothly, producing the corresponding Knoevenagel products in high to excellent yields.
