Selective C–C and C–H Bond Activation/Cleavage of Pinene Derivatives: Synthesis of Enantiopure Cyclohexenone Scaffolds a...
Published in Journal of the American Chemical Society
The continued development of transition-metal-mediated C-C bond activation/cleavage methods would provide even more opportunities to implement novel synthetic strategies. We have explored the Rh(I)-catalyzed C-C activation of cyclobutanols resident in hydroxylated derivatives of pinene, which proceed in a complementary manner to the C-C bond cleava...
Stereodivergent Intramolecular C(sp3)–H Functionalization of Azavinyl Carbenes: Synthesis of Saturated Heterocycles and ...
Published in Journal of the American Chemical Society
A general approach for the formation of five-membered saturated heterocycles by intramolecular C(sp3)–H functionalization is reported. Using N-sulfonyltriazoles as Rh(II) azavinyl carbene equivalents, a wide variety of stereodefined cis-2,3-disubstituted tetrahydrofurans were obtained with good to excellent diastereoselectivity from readily availab...
