Efficient synthesis of 5-aryl-2-vinylfurans by palladium catalyzed cross-coupling strategies
摘要:
The synthesis of substituted 5-aryl-2-furfurals from furfural by three alternative palladium cross coupling strategies are described. The resulting 5-aryl-2-furfurals were converted into their corresponding 5-aryl-2-vinylfurans in good yields by Wittig chemistry, (C) 1999 Elsevier Science Ltd. All rights reserved.

A novel nickel-catalyzed asymmetric 1,2-vinylboration reaction has been developed to afford benzylic alkenylboration products with high yields and excellent enantioselectivities by using a chiral bisoxazoline ligand. Under optimized conditions, a wide variety of chiral 2-boryl-1,1-arylvinylalkanes are efficiently prepared from readily available olefins and vinyl halides in the presence of bis(pinacolato)diboron

A NiH‐catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using
