摘要:
Disclosed is a process of making compounds of formula(I): wherein R1, R2, R3, R4 and Ra of formula(I) are defined herein. The product compounds inhibit production of cytokines involved in inflammatory processes and are thus useful for treating diseases and pathological conditions involving inflammation. Also disclosed are intermediates useful in making such compounds.
摘要:
Disclosed are highly convergent processes for preparing compounds of formula (I), which compounds are potent active agents for the treatment of hepatitis C virus (HCV) infection: The disclosed processes use SNAr-type coupling reactions between peptidic compounds having a hydroxyproline moiety of the following formula: and halogenated or sulfonated bromoquinoline compounds.

摘要:
The invention relates to a series of novel chiral nitrogen-phosphorus ligands of formulae (Ia) and (Ib): wherein R1-R3 and X are as defined herein. The invention also relates to chiral metal complexes prepared with these chiral nitrogen-phosphorus ligands. The chiral metal complexes are useful as catalysts for carrying out asymmetric hydrogenation.
摘要:
Disclosed are novel ruthenium compounds of formula (Ia) and (Ib): wherein R1 and the moiety are defined herein. Also disclosed is a process for using these novel ruthenium compounds as catalysts for asymmetric hydrogenation and transfer hydrogenation of ketones with high reactivities and excellent selectivities.
摘要:
Disclosed is a process for preparing substituted anisidines of formula I starting from substituted cyclic hydroxy-ketones II via aromatization through a substituted oxime intermediate IV in which R is C1-C6 alkyl or halogen, and Alk is C1-C6 alkyl. The substituted anisidines of formula I have been found to be useful as intermediates in the preparation of agents for the treatment of hepatitis C viral (HCV) infections.
