Description

Reaction of various kinds of alkyl alkoxycarbonylthiocarbamates (V) with ammonia gave 1-alkoxycarbony1-2-alkylpseudoureas (IV) in a good yield accompanying desulfurization. New 1-alkoxycarbony1-3-alkyl (or phenyl) carbamoy1-2-alkylpseudoureas (VII) were synthesized by the addition reaction of IV to alkyl (or phenyl) isocyanates. Nuclear magnetic resonance (NMR) spectra of 2-ethy1-1-methoxycarbony1-3-methy1-carbamoy1-pseudourea revealed that the compounds exist in two tautomeric forms in a solvent.
