6,11-dihydrodibenz[b,e]oxepins of formula:
in which R2 and R3 are hydrogen, halogen, CF3 or various N-, O- or S- attached substituents; R4 is hydrogen or various N-, O- or S- attached substituents and R5 is hydrogen or C1-4 alkyl, or R4 and R5 are together oxo, methylene or aryl-substituted methylene; and R1 is 5-tetrazolyl, 3-hydroxy-1,2,5-thiadiazol-4-yl, 4-hydroxy-Δ3- pyrroline-2,5-dione-3-yl or
where R6 is certain O- or N-attached residues, including hydroxy and 2-imino-3-methylthiazolidine, are useful in treating disease, particularly allergic diseases such as asthma. To this end they may be made up into pharmaceutical compositions. Certain of the compounds are novel.
The compounds are made by various routes, depending on the nature of the substituents.
式中的 6,11-二氢二苯并[b,e]氧杂卓类:
其中 R2 和 R3 是氢、卤素、CF3 或各种 N-、O-或 S-相连的取代基;R4 是氢或各种 N-、O-或 S-相连的取代基,R5 是氢或 C1-4 烷基,或 R4 和 R5 一起是氧代、亚甲基或芳基取代的亚甲基;R1 是 5-四唑基、3-羟基-1,2,5-噻二唑-4-基、4-羟基-Δ3-吡咯啉-2,5-二酮-3-基或: R6 是某些 O-或 N-相连的残基,包括羟基和 2-亚氨基-3-甲基噻唑啉基。
