This invention relates to novel dibenzo[d,g][1,3,6]dioxazocine derivatives represented by the general formula I ##STR1## wherein R.sub.1 and R.sub.2 independently represent hydrogen, halogen, cyano or trifluoromethyl, Y stands for hydrogen or a group of formula ##STR2## wherein A stands for a straight or branched chained alkylene having from 2 to 5 carbon atoms and R.sub.3 and R.sub.4 independently stand for an alkyl having from 1 to 4 carbon atoms, or R.sub.3 and R.sub.4 together with the nitrogen atom they are attached to and optionally together with a further nitrogen atom or with an additional oxygen atom may form a five- or six-membered heterocyclic ring optionally substituted with an alkyl having from 1 to 4 carbon atoms, and pharmaceutically acceptable acid addition salts thereof formed with an inorganic or organic acid. The above compounds possess valuable pharmaceutical properties, for instance they are effective local anaesthetics and can be used for treating Parkinson syndrome.
该发明涉及一种由通式I表示的新型二苯并[d,g][1,3,6]二噁唑啉衍生物,其中R.sub.1和R.sub.2独立地代表氢、卤素、氰基或三氟甲基,Y代表氢或具有通式的基团##STR2##其中A代表具有2到5个碳原子的直链或支链烷基,R.sub.3和R.sub.4独立地代表具有1到4个碳原子的烷基,或者R.sub.3和R.sub.4与它们所连接的氮原子一起,并且可选地与另一个氮原子或额外的氧原子一起形成一个含有1到4个碳原子的烷基的五元或六元杂环环,其与无机或有机酸形成的药用可接受的酸加盐。上述化合物具有有价值的药物特性,例如它们是有效的局部麻醉剂,可用于治疗帕金森综合症。
