A palladium‐catalyzed γ‐C(sp3)–H acetoxylation of triflyl‐protected amines has been achieved. The use of pyridine or 2‐alkoxyquinoline‐type ligands is key to the success of this transformation. The reaction is highly diastereoselective and easily scalable, and constitutes a direct approach for the synthesis of γ‐hydroxy‐α‐amino acids and β,γ‐dihydroxy amines, which are not readily accessible by other
已经实现了钯催化的三氟甲基保护胺的γ-C(sp3)-H乙酰氧基化。使用吡啶或 2-烷氧基喹啉型配体是这种转化成功的关键。该反应具有高度非对映选择性且易于扩展,并且构成了合成 γ-羟基-α-氨基酸和 β,γ-二羟基胺的直接方法,而其他途径不易获得。
