Synthesis of substituted benzo[d]thiazol-2-ylcarbamates as potential anticonvulsants
摘要:
A series of substituted benzo[d]thiazol-2-ylcarbamates 4a-g and 5a-g were synthesized and evaluated for anticonvulsant activity. The structures of the synthesized compounds were confirmed on the basis of their physical and spectral data. The compounds were evaluated for anticonvulsant activity using PTZ-induced convulsion and maximal electroshock models. The target compounds have shown significant activity in these models.

An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.
A series of fused bicyclic 2-aminothiazolyl compounds were synthesized and evaluated for their synergistic effects with polymyxin B (PB) against Klebsiella pneumoniae (SIPI-KPN-1712).

N,N,N″-Trisubstituted guanidines (most of them N″-aryl-N-azacycloalkanecarboximidamides) are prepared in generally good yields by S-methylation of monosubstituted thioureas with methyl iodide in methanol or acetone and reaction of the resultant methyl carbamimidothioate hydroiodides with secondary amines in boiling tert-butyl alcohol or acetonitrile.
