Rhodium-Catalyzed Domino Conjugate Addition-Cyclization Reactions for the Synthesis of a Variety of N- and O-Heterocycles: Arylboroxines as Effective Carbon Nucleophiles

초록

Facile and efficient Rh(I)-catalyzed domino conjugate addition-cyclization reactions of olefins bearing two electrophilic sites and a pendant nucleophile with organoboroxines have been developed to afford a variety of N- and O-heterocycles, such as 3,4-dihydroquinolin-2(1H)-ones, 3,4-dihydrocoumarins, and pyrrolidin-2-ones, which constitute important motifs in biologically active natural and synthetic organic compounds.
