Synthesis of substituted naphthalenes and carbazoles by the palladium-catalyzed annulation of internal alkynes

Huang, Qinhua,Larock, Richard C.

, p. 7342 - 7349 (2003)

An efficient synthesis of highly substituted naphthalenes has been developed by the palladium-catalyzed annulation of a variety of internal alkynes, in which two new carbon-carbon bonds are formed in a single step under relatively mild reaction conditions
