The rhodium(III)-catalyzed direct alkenylation of N-phenylindole-3-carboxylic acids with alkenes including acrylate ester, acrylamide, and acrylonitrile proceeds smoothly at the C4-position through regioselective C–H bondcleavagedirected by the carboxyl group. In marked contrast, the indole substrates react with diarylacetylenes accompanied by cleavage of the C2–H and C2′–H bonds and decarboxylation
Regioselective C−H Functionalization Directed by a Removable Carboxyl Group: Palladium-Catalyzed Vinylation at the Unusual Position of Indole and Related Heteroaromatic Rings
The palladium-catalyzed oxidative vinylation of indole-3-carboxylic acids with alkenes effectively proceeds via directedC-H functionalization and decarboxylation to produce the corresponding 2-vinylated indoles. Similarly, pyrrole-, furan-, and thiophenecarboxylic acids also undergo decarboxylative vinylation.
The present invention relates to a novel amide derivative. More specifically, the present invention provides a medicinal agent useful as a prophylactic or therapeutic agent for diseases, which relies on the production of cytokines from T cells, and which comprises an amide derivative or a pharmacologically acceptable salt thereof or a solvate of the derivative or the pharmacologically acceptable salt as an active ingredient. Provided is an amide derivative represented by general formula (I)
[wherein each symbol is as defined in the description] or a pharmacologically acceptable salt thereof, or a solvate of the derivative or the pharmacologically acceptable salt.
