Synthesis and Structure of 2-Nitroxyethylsuccinylaminodiethylmalonate

Interaction of hydroxymethylnitrodiethylmalonate with ammonia produced, in contrast to published data, the ammonium salt of nitrodiethylmalonate; catalytic reduction of this compound with hydrogen followed by treatment with the chloranhydride of the 2-nitroxyethyl ester of succinamic acid yielded 2-nitroxyethylsuccinylaminodiethylmalonate. The final structures of the ammonium salt of nitrodiethylmalonate and 2-nitroxyethylsuccinylaminodiethylmalonate were identified by x-ray diffraction analysis.
