The Cycloadditions of Nitrones with Fluoroallene

Article abstract of DOI:10.1021/jo00387a015

Cycloadditions of nitrones with fluoroallene proceed regiospecifically and with a remarkable stereochemical preference for addition syn to the fluorine substituent.The effects of solvent polarity on the rates and stereochemistry of these cycloadditions are reported and discussed.In general these effects are consistent with those reported for other nitrone cycloadditions, and the activation parameters are also similar.
