The invention relates to pyrrolopyrazine-spirocyclic piperidine amide compounds useful as inhibitors of ion channels. The invention also provides pharmaceutically acceptable compositions comprising the compounds of the invention and methods of using the compositions in the treatment of various disorders.
The invention provides an RORγ receptor agonist comprising a compound of formula (I), wherein the variables are as defined herein. These compounds are analogous to known RORγ receptor antagonists. The invention further provides a method of activating -the nuclear receptor RORγ, comprising -contacting the RORγ with an effective amount or concentration of a compound of the invention; and a method of treating cancer in a patient, comprising administering to the patient an effective dose of a compound of the invention.
The invention relates to sulfonamide derivatives, to their use in medicine, to compositions containing them, to processes for their preparation and to intermediates used in such processes.
More particularly the invention relates to a new sulfonamide Nav1.7 inhibitors of formula (I):

Singlet nucleophilic carbenes (SNCs) containing only one heteroatom donor remain underutilized in chemical synthesis. We recently discovered that visible-light-induced SNC intermediates can be trapped by fluorinated ketones via 1,2-carbonyl addition to afford benzoin-type products. This discovery represents a rare example of nucleophilic carbenes reacting with ketones and delivers an efficient, user-friendly

A direct intermolecular cross-benzoin-type condensation catalyzed by an N-heterocyclic carbene has been developed. The cross-coupling of commercially available aromaticaldehydes and trifluoromethyl ketones results in α-hydroxy-α-trifluoromethyl ketones bearing a quaternary stereocenter with excellent chemoselectivity and good to excellent yields.
