NOVEL 5 OR 8-SUBSTITUTED IMIDAZO [1, 5-a] PYRIDINES AS INDOLEAMINE AND/OR TRYPTOPHANE 2, 3-DIOXYGENASES
-
Paragraph 0382, (2016/10/31)
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.
Converting core compounds into building blocks: The concept of regiochemically exhaustive functionalization

In a model study, 3-fluorophenol and 3-fluoropyridine were converted into the each time four possible carboxylic acids by passing through the corresponding organometallic intermediates. As an attempt to generalize the findings reveals, a restricted set of principles and methods suffices to cope with all standard scenarios. The most valuable and versatile tools for the regiochemically exhaustive functionalization of a great variety of substrate patterns are the optionally site-selective metalation (either by reagent/substrate matching or by peripheral coordination control), the use of activating or congesting protective groups and the basicity gradient-driven heavy halogen migration (followed by halogen/metal permutation).
