Effect of the α-alkyl substituent of conjugated nitroolefins on the formation of cyclic nitronic esters vs. nitrocyclopropanes in their reaction with sulfur ylides

Article abstract of DOI:10.1055/s-1995-4137

The formation of cyclic nitronic esters (isoxazoline N-oxides) vs. nitrocyclopropanes in the reaction of conjugated nitroolefins with sulfur ylides depends on the presence of an α-alkyl substituent in the conjugated nitroolefins.
