Synthesis of alkynyl-substituted pyrrolidin-1-yloxyl radicals from 1-pyrroline N-oxide nitrones and alkynylmagnesium bromides

Article abstract of DOI:10.1055/s-1996-4199

The reaction of 1-pyrroline N-oxides with propargyl- and alkynyl-magnesium bromides proceed to give alkynyl functionalized pyrrolidin-1-oxyls without the formation of isoxazolines by a dipolar cycloaddition reaction.
