A highly efficient and general nucleophilic substitution reaction between dialkyl H-phosphonates or diarylphosphine oxides and triarylmethanols catalyzed by HOTf (trifluoromethanesulfonic acid) has been developed. It provides an atom-economical protocol for the synthesis of various symmetrical and unsymmetrical phosphorus-substituted triarylmethanes that constitute an emerging family of potent anticancer
已经开发了由HOTf(三氟甲磺酸)催化的H-膦酸二烷基酯或二芳基膦氧化物与三芳基甲醇之间的高效且通用的亲核取代反应。它为合成各种对称和不对称的磷取代的三芳基甲烷提供了一种原子经济的方法,这些化合物构成了新兴的强效抗癌剂家族,具有丰富的多样性,产率为40%至96%。该协议的综合适用性已通过克量级的制备证明。
