In this work, we described a preparation of substituted 2-aminothiazoles by two different methods using a one-pot procedure and starting from methoxymethylene-3-aryl-thiourea (2). The synthesized 2-aminothiazoles (5a-h) were characterized on the basis of elemental analysis and their spectral (IR, 1H NMR and 13C NMR) data and evaluated their biological activities. The majority of compounds were found to exhibit significant antimicrobial activity.

efficient one-pot method for the synthesis of 2-aminothiazoles using simple starting materials like isothiocyanates, amidines/guanidines and various halomethylenes is reported. The synthesis of 2-aminothiazoles involvesreactions such as nucleophilic addition, S-alkylation and intramolecular nucleophilic substitution in which amines departs as the leaving group.
A one-pot, three-componentprotocol for the synthesis of 2-aminothiazoles promoted by iodine from readily available starting materials such as b-diketones/b-ketoesters, arylamines, and NH4SCN has been developed. A wide range of arylamines was tolerated well to produce the expected polysubstituted 2-aminothiazoles in moderate to good yields. The characteristic features of this methodology include operational

A series of 2-amino-5-benzoyl-4-phenylthiazole derivatives was investigated in radioligand binding studies at adenosine receptor (AdoR) subtypes with the goal to obtain potent and A(1)-selective antagonists. Acylation of the 2-amino group was found to be crucial for high A(1) affinity. The best compound of the present series was 2-benzoylamino-5-p-methylbenzoyl-4-phenylthiazole (16m) showing a K-i value of 4.83 nM at rat and 57.4 nM at human A(1) receptors combined with high selectivity versus the other AdoR subtypes. The compound behaved as an antagonist in GTP shift assays at A(1) receptors. Compound 16m may serve as a new lead structure for the development of second-generation non-xanthine-derived A(1) antagonists which have potential as novel drugs. (C) 2010 Elsevier Ltd.
