The catalytic resolution of racemic cyclic amines has been achieved by an enantioselective amidation reaction featuring an achiral N-heterocyclic carbene catalyst and a new chiral hydroxamic acid cocatalyst working in concert. The reactions proceed at room temperature, do not generate nonvolatile byproducts, and provide enantioenriched amines by aqueous extraction.
外消旋环胺的催化拆分是通过对映选择性酰胺化反应实现的,该反应具有非手性 N-杂环卡宾催化剂和新型手性异羟肟酸助催化剂协同作用。反应在室温下进行,不产生非挥发性副产物,并通过水萃取提供富含对映体的胺。
