nucleophiles for SRN1 reactions with p-nitrobenzyl chloride, 2,2-dinitropropane and 1-methyl-2-chloromethyl-5-nitroimidazole. From C-alkylation products, base-promoted nitrous acid elimination and electron-transfer elimination of the two nitro groups afford new tetrahydro-1,3-oxazines with respectively a tri- and tetrasubstituted double bond at the 5 position. These new tetrahydro-1,3-oxazines can be hydrolysed
