The addition of carbamoyl anions derived from N,N-disubstituted formamides and LDA to N-tert-butyl nitrones is described. The reaction was demonstrated with a variety of formamides and nitrones and provided a direct route to α-(N-hydroxy)amino amides. The use of a tert-leucinol derived chiral auxiliary on the nitrone provided products in good diastereoselectivity. Derivatization of the products by
氨基甲酰基阴离子的衍生自除Ñ,Ñ二取代的甲酰胺和LDA到ñ -叔丁基硝酮进行说明。用多种甲酰胺和硝酮证明了该反应,并提供了直接通往α-(N-羟基)氨基酰胺的途径。在叔胺上使用叔亮氨酸衍生的手性助剂可提供具有良好非对映选择性的产物。证明了通过叔丁基脱保护或N-脱氧使产物衍生化。
