The enantioselective reduction of 1,3-dipolar nitrones to hydroxylamines was achieved by Rh(III)-catalyzed asymmetric hydrogenation and transfer hydrogenation. A wide range of chiral N,N-disubstituted hydroxylamines were synthesized with up to 99 % yield and >99 % ee. Mechanistic investigations and DFT calculations were conducted to elucidate the origin of reactivity and enantioselectivity.
通过 Rh(III) 催化的不对称氢化和转移氢化实现了 1,3-偶极硝酮对映选择性还原为羟胺。合成了多种手性N , N-二取代羟胺,产率高达 99%,ee >99%。进行了机理研究和 DFT 计算,以阐明反应性和对映选择性的起源。
