Chiral rhodium(I)‐catalyzed highly enantioselective arylation of aliphatic N‐sulfonyl aldimines with arylboronic acids has been developed. This transformation is achieved by the use of a rhodium/bis(phosphoramidite) catalyst to give enantiomerically enriched α‐branched amines (up to 99 % ee). In addition, this system enables efficient synthesis of (+)‐NPS R‐568 and Cinacalcet which are calcimimetic
已经开发了手性铑(I)催化的脂肪族N-磺酰基醛亚胺与芳基硼酸的高度对映选择性芳基化反应。通过使用铑/双(亚磷酰胺)催化剂可实现对映异构体富集的α-支化胺(最高ee达99%)的转化 。此外,该系统还可以高效合成拟钙剂(+)-NPS R-568和Cinacalcet。
