Palladium-Catalyzed Heteroarylation and Concomitant ortho-Alkylation of Aryl Iodides.
Three-component couplings were achieved from common aryl halides, alkyl halides, and heteroarenes under palladium and norbornene co-catalysis. The reaction forges hindered aryl-heteroaryl bonds and introduces ortho-alkyl groups to aryl rings. Various heterocycles such as oxazoles, thiazoles and thiophenes underwent efficient coupling. The heteroarenes were deprotonated in situ by bases without ...
متن کاملPalladium-catalyzed difluoromethylation of heteroaryl chlorides, bromides and iodides.
A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of d...
متن کاملPalladium-catalyzed difluoromethylthiolation of heteroaryl bromides, iodides, triflates and aryl iodides
A palladium-catalyzed difluoromethylthiolation of heteroaryl halides and triflates under mild conditions was described. A vast range of heteroaryl halides such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl and pyazolyl halides could be difluoromethylthiolated efficiently, thus providing medicinal chemists with new tools for their search of new lead compounds for drug discovery....
متن کاملPalladium-catalyzed asymmetric coupling cyclization of terminal γ-allenols with aryl iodides.
A Pd-catalyzed asymmetric coupling cyclization of γ-allenols has been developed. Styrenyl derivatives can be prepared in 60-86% yields with ee values ranging from 85-92%.
متن کاملPalladium-catalyzed cross-coupling of aryl or vinyl iodides with ethyl diazoacetate.
Palladium catalyzed cross-coupling reaction has been developed into one of the most powerful methods for the formation of C-C bonds.1 Recently, remarkable progress has been made in the Pdcatalyzed cross-coupling reactions with carbon nucleophiles derived from active methylene compounds,1d ketones,2 esters,3 amides,4 and nitriles.5 Hydrazones have also been applied in this type of reactions as a...
