Heterocyclic nitronate anions prepared from 3-ethyl-5-hydroxymethyl-5-nitrotetrahydro-1,3-oxazine are found to be suitable nucleophiles for SRNl reactions. Base-promoted nitrous acid elimination from C-alkylation product gives rise to new tetrahydro-1,3 oxazines with a trisubstituted ethylenic doubl
