The synthesis of α‐aminosilanes by a highly enantio‐ and regioselective copper‐catalyzed hydroamination of vinylsilanes is reported. The system employs Cu‐DTBM‐SEGPHOS as the catalyst, diethoxymethylsilane as the stoichiometric reductant, and O‐benzoylhydroxylamines as the electrophilic nitrogen source. This hydroamination reaction is compatible with differentially substituted vinylsilanes, thus providing
据报道,通过高度对映和区域选择性的铜催化的乙烯基硅烷加氢胺化反应合成α-氨基硅烷。该系统使用Cu-DTBM-SEGPHOS作为催化剂,使用二乙氧基甲基硅烷作为化学计量的还原剂,并使用O-苯甲酰基羟胺作为亲电子氮源。该加氢胺化反应可与差异取代的乙烯基硅烷相容,因此可提供氨基酸模拟物和其他有价值的手性有机硅化合物。
