We report herein, efficient and practical synthetic methods for the preparation of enantiomerically pure spiro[((2S)-hydroxy)indane-1,4'- piperidine] (S)-1, a key intermediate for the synthesis of a tachykinin receptor antagonist, using catalytic asymmetric reduction or catalytic asymmetric epoxidation as a key step.

Page/Page column 80; 81, (2018/10/19)
This invention relates to certain novel pyrazine derivatives (Formula I) as SHP2 inhibitors which is shown as formula I, their synthesis and their use for treating a SHP2 mediated disorder. More particularly, this invention is directed to fused heterocyclic group derivatives useful as inhibitors of SHP2, methods for producing such compounds and methods for treating a SHP2-mediated disorder.
