It has been established that a cationic gold(I)/(R)-H8-binap complex catalyzes the enantioselective intramolecular [4+2] annulation of benzene-linked ene-yne-carbonyls via benzopyrylium-type intermediates at room temperature to give chiral tric

An oxy-palladation, formal Wagner-Meerwein rearrangement and fluorination cascade has been established for generating fluorinated oxazolidine-2,4-diones and oxazolidin-2-ones. The reaction has a broad substrate scope in which both aryl and alkyl groups can be utilized as efficient migrating groups. Experimental evidence suggests that the reaction is initiated by anti-oxy-palladation of the olefin, followed by oxidative generation of an alkyl PdIV intermediate and a concerted migration-fluorination.
Au-catalyzed piperidine synthesis via tandem acyloxy migration/ intramolecular [3 + 2] cycloaddition of enynyl esters

An Au-catalyzed tandem protocol involving enynyl ester isomerization and subsequent intramolecular [3 + 2] cyclization has been developed. This strategy provides an efficient approach for the synthesis of polyfunctional piperidines, which are subunits of
