Abstract:	The reactions of HNO₃ with tetrahydro-1,3-oxazines 1a—c produced by aminomethylation of diketopiperazine, isatin, and succinimide, respectively, afforded nitrates of amino alcohols RCH₂NH₂(CH₂)₃ONO₂]⁺NO₃ ^– (4a—c) whose subsequent N-nitrosation (NaNO₂, AcOH) gave nitrates of N-nitrosoamino alcohols RCH₂N(NO)(CH₂)₃ONO₂ (5a—c). The structures of compound 5b,c were established by X-ray diffraction analysis.
