An enantioselective synthesis of INCB018424 viaorganocatalytic asymmetric aza-Michael addition of pyrazoles (16 or 20) to (E)-3-cyclopentylacrylaldehyde (23) using diarylprolinol silyl ether as the catalyst was developed. Michael adducts (R)-24 and (R)-27 were isolated in good yield and high ee and were readily converted to INCB018424.
使用二芳基脯氨醇甲硅烷基醚作为催化剂,通过有机催化不对称氮杂-迈克尔加成将吡唑(16或20)与(E)-3-环戊基丙烯醛(23)进行对映选择性合成INCB018424 。迈克尔加合物 ( R )- 24和 ( R )- 27以良好的产率和高 ee 分离出来,并且很容易转化为 INCB018424。

The present invention is related to processes for preparing chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines of Formula III, and related synthetic intermediate compounds. The chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines are useful as inhibitors of the Janus Kinase family of protein tyrosine kinases (JAKs) for treatment of inflammatory diseases, myeloproliferative disorders, and other diseases.
