Applications of Heteroarylboron Compounds to Organic Synthesis

This report deals with our recent results concerning the reaction and synthetic application of boronsubstituted heteroaromatic compounds (1) palladium-catalyzed cross-coupling, carbonylative cross-coupling and tandem cyclization cross-coupling reactions with dialkylpyridylboranes and indolylborates, and their use in the preparation of heterocyclic derivatives and (2) the synthetic application of an intramolecular alkyl migration process in indolylborates for the construction of more elaborate indole derivatives.
