    • 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.
    • 描述了在1-位上带有羟基低级烷基取代基的三环苯并二氮杂衍生物(“A”)和苯并二氮杂部分位置4和5之间连接的杂环。 杂环将含有出现在苯并二氮杂环的第4位的氮原子以及与苯并二氮杂环的5-位的碳原子连接的可以是氧或氮的杂原子。 在新的杂环中带有氧原子的“A”可以通过在酸催化剂的存在下用环氧化合物处理由相应的4,5-不饱和的苯并二氮杂卟啉形成。 在新杂环中带有氮原子或氧原子的“A”可以通过相应的开放化合物的环化来制备。 “A”可用作镇静剂,肌肉松弛剂和抗惊厥剂。
