摘要

The synthesis of 4-substituted indazole derivatives by palladium-mediated cross-coupling reactions was described. Suzuki, Heck, Sonogashira and Stille cross-coupling reactions were used to introduce aryl, vinyl and alkynyl substituents in 4-position of indazole derivatives. The selectivity of bis-Suzuki reactions of 3, 4-diiodo-and 3-bromo-4- iodoindazoles was investigated.
