Nitrocyclopropane formation has been successfully carried out by reaction of bromonitromethane with electrophilic alkenes bearing two electron-withdrawing groups in the α- and β-positions, and in the presence of potassium carbonate as base. The method allows good yields and moderate to satisfactory diastereoselectivity with linear alkenes, while shows the complete formation of the exo-product with N-alkylmaleimides.

Abstract
Nitrocyclopropane formation has been successfully carried out by reaction of bromonitromethane with electrophilic alkenes bearing two electron-withdrawing groups in the α- and β-positions, and in the presence of potassium carbonate as base. The method allows good yields and moderate to satisfactory diastereoselectivity with linear alkenes, while shows the complete formation of the exo-product with N-alkylmaleimides.File in questo prodotto:
