Abstract:
An unprecedented Pd-catalyzed regioselective activation of gem-difluorinated cyclopropanes induced by C-C bond cleavage is reported. It provides a general and efficient access to a variety of 2-fluoroallylic amines, ethers, esters, and alkylation products in high Z-selectivity, which are important skeletons in many biologically active molecules. In addition, the transformation represents the first general application of gem-difluorinated cyclopropanes as reaction partners in transition-metal-catalyzed cross-coupling reaction.
