Disclosed herein are 5 or 8-substituted imidazo[l,5-a]pyridines and pharmaceutical compositions comprising at least one such 5 or 8-substituted imidazo[l,5-a]pyridines, processes for the preparation thereof, and the use thereof in therapy. Disclosed herein are certain 5 or 8- substituted imidazo[l,5-a]pyridines that can be useful for inhibiting indoleamine 2,3- dioxygenase and/or tryptophane 2,3-dioxygenase and for treating diseases or disorders mediated thereby.
Abstract γ-Methylene derivatives of α,β-unsaturatedketones are obtained readily by a one-pot procedure exploiting the reaction of O-silylated dienolates with commercially available formaldehyde N, N-dimethyliminium chloride in anhydrous N, N-dimethylformamide, in situ oxidation of the Mannich reaction product with hydrogenperoxide, and elimination of N,N-dimethylhydroxylamine from the resultant N-oxide

The carbocyclic core of CP-225,917 and CP-263,114 is accessible through the [6+4] cycloaddition of a tropone with a 2-substituted cyclopentadiene. Examination of this reaction has revealed for the first time that this cycloaddition process is catalyzed by Lewis acids, including lanthanide triflates. Cycloadditions of several mono-, di-, and trisubstituted tropones with 2-silyloxycyclopentadienes using
