Piperidines are prevalent in natural products and pharmaceutical agents and are important synthetic targets for drug discovery and development. We report on a methodology that provides highly substituted piperidine derivatives with regiochemistry selectively tunable by varying the strength of acid...

Readily available 1-mesyl-1,2,3-triazoles are efficiently converted into a variety of imidazolones and thiazoles by Rh(II)-catalyzed denitrogenative reactions with isocyanates and isothiocyanates, respectively. The proposed triazole-diazoimine equilibrium results in the formation of highly reactive azavinyl metal-carbenes, which react with heterocumulenes causing...

A straightforward and efficient method for the rhodium-catalyzed intermolecular oxidative cross-coupling of arenes and heteroarenes with thio- and selenophene derivatives (chalcogenophenes) via double C-H bond cleavage has been developed by using Cu(OAc)2/AgSbF6 as an oxidant. The reaction is applicable to...

A novel rhodium(III)-catalyzed direct functionalization of the ortho-C-H bond of aromatic ketone derivatives and an intramolecular cyclization sequence produced indene derivatives in moderate to good yields. This cascade cyclization involves a conjugate addition of α,β-unsaturated ketone and subsequent aldol condensation....
