Abstract
Process for obtaining 1-4-substituted semicarbacids, characterized by the reaction of a 1-p-nitrophenyl-2-amino-1,3-propanediol in a suitable solvent with an alkylidene or benzylidene aminoisocyanate to obtain compounds of the general formula ** (see formula) ** Where r represents a resulting group of carbonyl compound and that by elimination of oxygen and subsequent binding to nitrogen forms the group - n = r.
