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 agents.
已开发出一种手性铑(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(磷酰胺)催化剂实现这种转化,得到对映体富集的α-支链胺(对映体过量高达99%)。此外,该体系能够高效合成拟钙剂(+)-NPS R-568和西那卡塞。
