Intramolecular annulation of aromatic rings with N-sulfonyl 1,2,3-triazoles: divergent synthesis of 3-methylene-2,3-dihydrobenzofurans and 3-methylene-2,3-dihydroindoles
Zinc(<scp>ii</scp>)-catalyzed intramolecular hydroarylation-redox cross-dehydrogenative coupling of<i>N</i>-propargylanilines with diverse carbon pronucleophiles: facile access to functionalized tetrahydroquinolines
Redox cross-dehydrogenative coupling ofN-propargylanilines with diverse carbon pronucleophiles offers a general and efficient synthetic method to construct functionalized tetrahydroquinolines.

This work reports gold-catalyzed oxidative alkenylations of quinoline N-oxides with propargyl aryl thioethers to afford 3-hydroxy-1-alkylidenephenylthiopropan-2-one via a 1,3-sulfur group migration. The mechanism of this reaction is postulated to involve an α-oxo gold carbene intermediate followed by formation of a four-membered sulfonium ring that is ring-opened by one H2O to form a gold enolate.
