Abstract
Process for obtaining new esters of carbaminic acid, of general formula I, ** (See formula) ** where R1 is by a cycloaliphatic moiety or a cycloaliphatically substituted alkyl moiety, R2 by an alkyl moiety with preferably 1-7 carbon atoms, a cycloaliphatic moiety or a cycloaliphatically substituted alkyl moiety and R3, R4, R5 and R6 by hydrogen or hydrocarbon moieties aliphatic with preferably 1-4 carbon atoms, characterized in that in a diol of the formula IV ** (See formula) ** where R1 and R2 have the meaning indicated above, the hydroxyl groups are transformed, in a manner known per se, into carbamyloxy groups of the abovementioned kind.
