An efficient and rapid synthetic approach for the synthesis of tetrazolo[1,5-a]quinolines has been developed employing the reaction of o-alkynylisocyanobenzenes with sodium azide. The present strategy involved nucleophilic addition of azide to isocyanide followed by 6-endo cyclization. The reaction gives access to a collection of tetrazolo[1,5-a]quinolines with broad functional group in moderate to high yields under metal-, and base-free conditions.

An unprecedented palladium-catalyzed oxidative annulation of acrylamides with benzyne precursors has been successfully developed. By using this mild "N-H activation/Heck reaction" method, a wide variety of quinolinones were conveniently prepared in one st

experimental part, p. 4249 - 4263 (2010/01/15)
A short, efficient, and high-yielding synthesis of 4-aryl-2-aminopyridine derivatives has been developed. The route employs two palladium-catalyzed processes, the Suzuki reaction and the Buchwald-Hartwig amination, as the key steps. The same approach has
