The reaction of ethyl 4'-amino-1'H-spiro[cycloheptane-1,2'-naphthalene]-3'-carboxylate and benzylisothiocyanate followed by cyclization of the intermediate thiourea synthesized 3-benzyl-2-thioxo-2,3-dihydro-1H-spiro[benzo[h]quinazoline-5,1'-cycloheptane]-4(6H)-one, which was alkylated in the presence of alkali to give 2-alkylthio-substituted 3-benzyl-3H-spiro[benzo[h]quinazoline-5,1'-cycloheptane]-4(6H)-ones. The antitumor activity (against Ehrlich's ascites carcinoma and sarcoma 180) and antibacterial properties of the synthesized compounds were studied using Gram-positive (S. aureus 209p and 1) and Gram-negative microbes (S. flexneri 6858 and E. coli 0-55) as test objects.
