A chiral complex derived from (S)-difluorophos and Hg(OTf)2 is identified as a powerful catalyst for the Sakurai–Hosomi reaction of isatins with allyltrimethylsilane, allowing the facile synthesis of valuable building blocks 3-allyl-3-hydroxyoxindoles in up to 97% ee, with only 0.5–1.0 mol% of catalyst loading.
从(S)-二氟膦和Hg(OTf)2衍生的手性配合物被确定为Sakurai-Hosomi反应的强力催化剂,用于isatins与烯丙基三甲基硅烷的反应,可轻松合成有价值的3-烯丙基-3-羟基喹啉酮建筑块,其ee值高达97%,仅需0.5-1.0 mol%的催化剂负载。
