Abstract

An efficient stereoselective method towards the construction of isoxazolidine-cis-fused phosphadihydrocoumarins frameworks involving an intermolecular 1,3-dipolar nitrone cycloaddition reaction utilizing O-vinylphosphonylated salicylaldehydes and N-substituted hydroxylamines in situ formation of Nitrone–Vinylphosphonate bifunctional intermediates under catalyst free condition have been described.
