摘要:
The present invention provides a method of resolving piperdin-yl-alkylene-alcohols, in high yield at high enantiomeric purity, for example 2-piperidin-2-yl-ethanol.
摘要:
This application discloses a novel process for the preparation of himbacine analogs useful as thrombin receptor antagonists. The process is based in part on the use of a base-promoted dynamic epimerization of a chiral nitro center. The chemistry taught herein can be exemplified by the following:
摘要:
The present invention relates to synthetic processes useful in the preparation of compounds of Formula (I) that are useful as inhibitors of the hepatitis C virus (HCV) NS3 protease and have application in the treatment of conditions caused by HCV. In particular, the present invention relates to novel oxidation processes useful for preparing compounds of Formula (I) and related compounds, including pharmaceutically acceptable salts, hydrates and solvates thereof, and including stereoisomers thereof.
摘要:
This application discloses a novel process to synthesize (3-alkyl-5-piperidin-1-yl-3,3a-dihydro-pyrazolo[1,5-a]pyrimidin-7-yl)-amino derivatives, and intermediates useful in the synthesis thereof. The subject (3-alkyl-5-piperidin-1-yl-3,3a-dihydro-pyrazolo[1,5-a]pyrimidin-7-yl)-amino derivatives are useful as cyclin-dependent kinase inhibitor compounds (CDK inhibitors) in pharmaceutical preparations.
摘要:
The present application relates to a process for preparing a compound of formula I: wherein R1 is alkyl; R2 is alkyl; and R3 is optionally substituted cycloalklylalkyl which comprises oxidizing a compound of the formula wherein R1, R2 and R3 are defined above to yield a compound of formula I.
