An efficient and highly enantioselective copper‐catalyzed allylic alkylation of phosphonates and phosphine oxides with Grignard reagents and Taniaphos or phosphoramidites as chiral ligands is reported. Transformation of these products leads to a variety of new phosphorus‐containing chiral intermediates.
据报道,使用格氏试剂和三苯氧磷或亚磷酰胺作为手性配体,可有效且高度对映体选择性地催化铜催化的膦酸酯和氧化膦的烯丙基烷基化反应。这些产品的转化产生了各种新的含磷手性中间体。
