Vinylation of the Indole 3-Position via Palladium-catalyzes Cross-Coupling
Heterocycles1994Vol. 37(3), pp. 1761–1761
Abstract
The palladium-catalyzed cross-coupling between 3-indoleboronic acids and vinyl triflates is an excellent method fror the regioselective introduction of vinyl groups into the indole 3-position. The regioselectivity of the enolization of N-substituted 3-piperidones, as dictated by the nitrogen substituent, is far greater than previously reported. N-tosyl-3-indoleboronic acids can be easily synthesized using the mercuration-boronation method
