Abstract

N-Substituted 5-aza-2-oxa-3-oxo-bicyclo[2.2.1]heptanes are conformationally rigid models that have been used in several 1H-NMR studies. They have previously been obtained by multistep processes. We have devised a one step synthesis for these compounds. The utility of this new route has been demonstrated for five differently N-substituted substrates.
