Синтез и структура 2-нитроксиэтилсукциниламинодиэтилмалоната

In contrast to published data, the interaction of hydroxymethylnitrodiethylmalonate with ammonia yielded a nitrodiethylmalonate ammonium salt. The subsequent catalytic reduction with hydrogen, followed by the treatment with chloroanhydride of 2-nitroxyethyl ether of succinamic acid, converted this salt into 2-nitroxyethylsuccinylaminodiethylmalonate. The structures of the obtained nitrodiethylmalonate ammonium salt and 2-nitroxyethylsuccinylaminodiethylmalonate have been determined by x-ray diffraction.
