Abstract: Several urea and thiourea derivatives (2a-f) were prepared by the reaction of dihydronaphthopyrazolylbenzenesulfonamide (1) with the corresponding isocyanates and isothiocyanates, respectively. The benzene-sulfonylthioureas (2d,e) were cyclized with ethyl bromoacetate, ethyl beta-bromopropionate and alpha-bromoacetophenones to give the corresponding 4-oxothiazolidine (3a,b), 4-oxo-5,6-dihydrothiazine (4a,b) and thiazoline derivatives (5a-d) respectively. |
