direct and effective transformation of α-amino ketones, acetamides, and esters to the corresponding α-diazo products under mild basic conditions has been developed. This one-step synthetic approach not only allows for generation of α-substituted-α-diazo carbonyl compounds from α-amino acid derivatives but also permits preparation of α-diazo dipeptides from N-terminal dipeptides (32 examples, up to 91%)
开发了一种新型通用N-转移试剂,可在温和的碱性条件下直接有效地将 α-氨基酮、乙酰胺和酯转化为相应的 α-重氮产物。这种一步合成方法不仅允许从 α-氨基酸衍生物生成 α-取代-α-重氮羰基化合物,而且允许从N-末端二肽制备 α-重氮二肽(32 个例子,高达 91%) .
