Abstract
The invention comprises hydantoins of the general formula <FORM:0764146/IV(b)/1> where R1 and R2 are the same or different hydrocarbon radicals, any aliphatic chains of which can be interrupted by O or S and/or any aromatic nuclei of which can be halogen or alkoxy substituted, and which can be linked to each other, and their preparation by heating the dihydrazide or an ester of a monohydrazide of a C,C-disubstituted glycine-N-carboxylic acid in the presence or absence of solvents or diluents. A specific diluent is water, this being gradually distilled off to remove continuously the liberated hydrazine. Examples describe the preparation, by heating a di-lower alkyl ester of the appropriate C,C-disubstituted glycine-N-carboxylic acid with excess hydrazine hydrate in absolute ethanol or methanol, distilling off the solvent and concentrating an aqueous solution of the dihydrazide residue by heating, of the following compounds of the above general formula in which R1 and R2 in the same compound have the values: dimethyl, methyl - iso - butyl, diethyl, ethyl - n - butyl, methyl-n-hexyl, pentamethylene, and methylbenzyl. The following 5,5-disubstituted-3-amino hydantions are also referred to: methylethyl, methyl-n-propyl, ethyl-n-amyl, methylcyclopropyl, methyl - phenyl, ethyl - phenyl, diphenyl, methyl - allyl, ethyl - cyclohexenyl, methyl - p - chlorophenyl, methyl - p - methoxyphenyl, methyl - b - phenoxyethyl, methylb -methylmercaptoethyl and methyl-sec-butyl. Starting material. N-carbethoxy-1-aminocyclohexane carboxylic acid ethyl ester is obtained by reacting 1-amino-cyclohexane carboxylic acid ethyl ester with chloroformic acid ethyl ester.
