efficient, metal-free highly stereoselective reduction of ketimines to chiral amines was developed. Different imines bearing a very cheap and removable chiral auxiliary were reduced simply by trichlorosilane in the presence of N,N-dimethyl-formamide, often in quantitative yield and complete control of the absolute stereochemistry, to afford highly enantiomerically enriched amines.
开发了一种低成本、高效、无金属的高度立体选择性还原酮亚胺为手性胺。在 N,N-二甲基甲酰胺存在下,通过三氯硅烷简单地还原带有非常便宜且可去除的手性助剂的不同亚胺,通常以定量收率和完全控制绝对立体化学,提供高度对映体富集的胺。
