2. Ring-Opening of Donor-Acceptor Cyclopropanes by Boronic Acids and Potassium Organotrifluoroborates under Transition-Metal-Free Conditions.

Author

Ortega, Víctor and Csákÿ, Aurelio G.

Abstract

The ring-opening of cyclopropane-1,1-dicarboxylates with vicinal donor aryl groups by boronic acids and potassium organotrifluoroborates under metal-free conditions has been developed. The reaction utilizes trifluoroacetic acid or boron trifluoride as promoters. [ABSTRACT FROM AUTHOR]

Abstract

The substrate-controlled 1,3-stereoselective conjugate addition of boronic acids and potassium trifluoroborates under metal-free conditions has been developed. This reaction affords bicyclic acetals, which have been used as key intermediates in the stereodivergent synthesis of polysubstituted tetrahydropyrans. [ABSTRACT FROM AUTHOR]
