Tricyclic benzodiazepine derivatives (A) bearing a hydroxylower alkyl substituent in the 1-position and a heterocyclic ring joined between positions 4 and 5 of the benzodiazepine moiety are described. The heterocyclic ring will contain the nitrogen atom appearing at position 4 of the benzodiazepine ring as well as the hetero atom, which may be either oxygen or nitrogen, attached to the carbon atom at the 5-position of the benzodiazepine ring. "A" bearing an oxygen atom in the new heterocyclic ring may be formed from the corresponding 4,5-unsaturated benzodiazepines by treatment with an epoxide compound in the presence of an acid catalyst. "A" bearing either a nitrogen or an oxygen atom in the new heterocyclic ring may be prepared by cyclization of the corresponding open compound. "A" are useful as sedative, muscle relaxant and anti-convulsant agents.
本文描述了一种三环苯二氮平衍生物(A),其1位带有羟基较低烷基取代基,且杂环环在苯二氮平基团的4和5位之间连接。杂环环将包含出现在苯二氮平环的4位的氮原子以及连接到苯二氮平环的5位碳原子的杂原子,可以是氧原子或氮原子。在新的杂环环中带有氧原子的“A”可以通过在存在酸催化剂的条件下用环氧化合物处理相应的4,5-不饱和苯二氮平制备而成。在新的杂环环中带有氮或氧原子的“A”可以通过相应的开放化合物的环化反应制备而成。这些“A”用作镇静剂、肌肉松弛剂和抗惊厥剂。
