A rhodium(III)‐catalyzed direct C−H alkynylation of a wide range of N‐methylsulfoximines with (bromoethynyl)triisopropylsilane has been developed. This protocol is compatible with both (S,S)‐diaryl sulfoximines and (S,S)‐alkyl aryl sulfoximines, and shows mild conditions, and good functional group tolerance. The synthetic utility of this method has been demonstrated by subsequent various transformations
已经开发出了铑(III)催化的N-甲基亚砜肟与(溴乙炔基)三异丙基硅烷的广泛CHN炔基化反应。此协议是与两者(兼容小号,小号)-diaryl亚磺酰亚胺和(小号,小号) -烷基芳基的亚磺酰亚胺,和节目温和的条件,和良好的官能团耐受性。该方法的合成效用已通过随后的各种产物转化得到证明。
