By the action of 2-amino-5-methylthio-1,3,4-thiadiazole, 3-amino-5-methylisoxazole, 2-amino-6-fluorobenzothiazole, 2-amino-5-chloropyridine, respectively, on 4-chloro-2-oxo-2H-chromene-3-sulfonyl chloride, the corresponding 9-methylthio-7,7-dioxo-7,7a-dihydro-5-oxo-7λ6,10-dithia-8,11-diaza-cyclopenta[b] phenantren-6-one, 9-methyl-7,7-dioxo-7H-5,8-dioxa-7λ6-thia-7a,11-diaza-cyclopenta[b] phenantren-6-one, 9-fluoro-7,7-dioxo-7H-5-oxa-7λ6,12-dithia-7a,13-diaza-indeno[1,2-b] phenantren-6-one and 9-Chloro-7,7-dioxo-7H-5-oxa-7λ6-thia-7a,12-diaza-benzo[α]anthracen -6-one were formed and they have been isolated in satisfying yields. Based on the biological activity of chromene-2-ones and heterocyclic compounds condensed in position 3 and 4, we also studied microbiological activity of these new compounds(5-8), againstStaphylococcus aureusATCC 25923,Streptococcus pneumoniae, Aeromonas Salmonicida, Bacillus sppand some of them exhibited significant activity.
通过2-氨基-5-甲基硫代-1,3,4-噻二唑、3-氨基-5-甲基异噁唑、2-氨基-6-氟苯并噻唑、2-氨基-5-氯吡啶分别作用于4-氯-2-氧代-2H-咔喱-3-磺酰氯,得到相应的9-甲基硫代-7,7-二氧-7,7a-二氢-5-氧-7λ6,10-二硫-8,11-双氮杂-环戊[b]菲南-6-酮、9-甲基-7,7-二氧-7H-5,8-二氧-7λ6-硫-7a,11-双氮杂-环戊[b]菲南-6-酮、9-氟-7,7-二氧-7H-5-氧-7λ6,12-二硫-7a,13-双氮杂-吲哚[1,2-b]菲南-6-酮和9-氯-7,7-二氧-7H-5-氧-7λ6-硫-7a,12-双氮杂-苯并[α]蒽-6-酮,并以令人满意的产率分离出来。基于2-酮基咔喱和在3和4位置上凝聚的杂环化合物的生物活性,我们还研究了这些新化合物(5-8)对金黄色葡萄球菌ATCC 25923、肺炎链球菌、鲑气单胞菌、芽孢杆菌等的微生物活性,并且其中一些表现出显著的活性。
