2-Oxo-hexahydroazepine, -piperidine and -pyrrolidine derivatives of general formula (I)
where n is 2, 3 or 4, R is hydrogen, lower alkyl or aryl(lower)alkyl and R' is hydrogen or lower alkyl are novel intermediates for their aromatised derivatives of formula (II)
where n and R' are as defined above, R2 is hydrogen, lower alkyl or aryl(lower)alkyl and R3 is hydrogen, lower alkyl, aryl(lower)alkyl, lower alkenyl or lower alkynyl. The aromatised derivatives (of which those in which R' is hydrogen are novel) can be converted into 3,3-disubstituted- hexahydroazepine, -piperidine and -pyrrolidine derivatives having pharmacological activity, particularly analgesic activity.
通式 (I) 的 2-氧代六氢氮杂卓、-哌啶和-吡咯烷衍生物
其中 n 为 2、3 或 4,R 为氢、低级烷基或芳基(低级)烷基,R'为氢或低级烷基,是通式(II)芳香化衍生物的新型中间体
其中 n 和 R' 如上定义,R2 是氢、低级烷基或芳基(低级)烷基,R3 是氢、低级烷基、芳基(低级)烷基、低级烯基或低级炔基。芳香化衍生物(其中 R' 为氢的衍生物为新型衍生物)可转化为具有药理活性,特别是镇痛活性的 3,3-二取代-六氢氮杂卓、-哌啶和-吡咯烷衍生物。
