for the synthesis of optically active heteroaryl α-(hydroxyamino) esters was explored. The highly diastereoselective addition of heteroaromatics to a cyclic chiral nitrone allowed access to a series of heteroaryl hydroxylamines. The scope of this reaction was evaluated on substrates possessing a pyrrole, an indole, or a furan core. The three-step sequence afforded the α-(hydroxyamino) esters in good
探索了合成光学活性杂芳基α-(羟基氨基)酯的实用序列。杂芳烃与环状手性硝酮的高度非对映选择性加成允许获得一系列杂芳基羟胺。该反应的范围是在具有吡咯、吲哚或呋喃核的底物上进行评估的。三步序列以良好的总产率 (36–62%) 提供了 α-(羟基氨基) 酯,具有良好的对映体过量值 (76 至 ≥98%)。
