5,5-Diamino-substituted-1,4,2-oxathiazoline derivatives 3 as potential prodrugs, which were easily prepared from hydroximoyl chlorides I and the appropriate thiourea derivatives 2, were decomposed instantaneously into isothiocyanates 4 and the corresponding urea derivatives 5 irrespective of the substituents.
Ureas from N-Chloroamidines; An Aza-Analogous Hofmann Degradation
Sonnenschein, Helmut,Schmitz, Ernst
, p. 443 - 444 (2007/10/02)
N-Chlorination and subsequent treatment with alkali of suitably substituted benzamidines yields ureas with phenyl or alkyl migration.Under the same conditions, 2-iminopyrrolidine is converted into 2-oxohexahydropyrimidine with ring enlargement.
THE INTRAMOLECULAR NH...Cl HYDROGEN BOND IN UREA DERIVATIVES CONTAINING THE o-CHLOROPHENYL GROUP
Mido, Yoshiyuki,Okuno, Tomoko
, p. 29 - 34 (2007/10/02)
The solution ν(N-H) vibrations of various disubstituted ureas containing a halophenyl group have been examined in order to directly confirm the presence of an intramolecular NH...Cl hydrogen bond in the o-chloro analog.In chlorophenyl derivatives the ν(N-
