The catalytic enantioselective electrophilic α-amination promoted by chiral bifunctional organocatalysts is described. Treatment of α-cyanoketones with azodicarboxylates as electrophilic amination reagents under mild reaction conditions afforded the corresponding α-aminated α-cyanoketones with excellent enantiomeric excesses (87-99%).
描述了手性双功能有机催化剂促进的催化对映选择性亲电α-胺化。在温和反应条件下用偶氮二
甲酸盐作为亲电子胺化试剂处理α-
氰酮,得到相应的α-胺化α-
氰酮,具有优异的对映体过量(87-99%)。
