iron(II) catalyst. Density functional theory calculations were used to examine the regioselectivity of arene C–H amination reactions on diversely substituted arenes. The calculations suggest a simple charge-controlled regioselectivity model that enables prediction of the major C(sp2)–Hamination product.
There are disclosed compounds of the following formula I:
or a stereoisomer or pharmaceutically acceptable salt thereof, wherein all substituents are as defined herein, which are useful in the modulation of IL-12, IL-23 and/or IFNα, by acting on Tyk-2 to cause signal transduction inhibition. The compounds of the invention may be useful for treating neurodegenerative diseases or disorders.
