Synthesis of Multicyclic Pyridine and Quinoline Derivatives via Intramolecular C−H Bond Functionalization
摘要:
An efficient method is reported for the preparation of multicyclic pyridines and quinolines by a rhodium-catalyzed intramolecular C H bond functionalization process. The method shows good scope for branched and unbranched alkyl substituents on the pyridine ring and at the R position of the tethered alkene group. Starting materials capable of undergoing olefin isomerization to provide terminal 1,1-disubstituted alkenes also proved to be effective substrates.
The present invention provides a compound having an ACC inhibitory action, which is useful as an agent for the prophylaxis or treatment of obesity, diabetes and the like, and having superior efficacy.
