6-H-Dibenz[b,e][1,4]oxathiepin derivatives of the formulae I and IA are novel. They can be used in the treatment and control of allergic conditions such as allergic asthma.
They are made by reducing the corresponding compound in which the (CH2)nOR4 residue is replaced by a (CH2)n-1COOH residue.
In the formula n is 1, 2, 3 or 4, Z is thia, sulfinyl or sulfonyl; each of R1, R2 and R3 is H, halogen, NH2, alkyl, alkylthio, alkylsulfinyl, alkylsulfonyl, CF3, CF3S, CN, N02, alkylamino, dialkylamino, alkoxy, alkanoyl, aralkyl, or hydroxyalkyl, or R1 and R2 together represent polymethylene, possibly oxo or hydroxy substituted; and R4 is H, acyl, alkylaminoacyl, alkylcarboxy, alkylcarbamoyl, alkylcarba- moylacyl or acyloxyalkyl.
式 I 和 IA 的 6-H-二苯并[b,e][1,4]氧硫杂环戊烷衍生物是一种新型衍生物。它们可用于治疗和控制过敏性疾病,如过敏性哮喘。
它们是通过还原相应的化合物制成的,其中的(CH2)nOR4残基被(CH2)n-1COOH残基取代。
式中 n 为 1、2、3 或 4,Z 为硫代、亚砜基或磺酰基;R1、R2 和 R3 各为 H、卤素、NH2、烷基、烷硫基、烷基亚砜基、烷基磺酰基、CF3、CF3S、CN、N02、烷基氨基、二烷基氨基、烷氧基、烷酰基、芳烷基或羟基烷基,或 R1 和 R2 共同代表可能被氧化或羟基取代的聚亚甲基;R4 是 H、酰基、烷基氨基酰基、烷基羧基、烷基氨基甲酰基、烷基羰基酰基或酰氧基烷基。
