Compounds of Formula I: and stereoisomers and pharmaceutically acceptable salts and solvates thereof in which R1, R2, R3 and R4 have the meanings given in the specification, are inhibitors of one or more JAK kinases and are useful in the treatment of JAK kinase-associated diseases and disorders, such as autoimmune diseases, inflammatory diseases, rejection of transplanted organs, tissues and cells, as well as hematologic disorders and malignancies and their co-morbidities.
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.

Tunable hydrophobicity: Efficient air filters for the protection against chemical warfare agents might be achieved by surface functionalization of the pores in robust metal–organicframeworks (MOFs) with fluoroalkyl residues and the precise control of their pore size (see picture). These MOFs captureharmfulvolatileorganiccompounds even under extremely moist conditions (80 % relative humidity).
