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.
描述了在三环苯二氮卓衍生物(“A”)中,1位位置带有一个氢氧基较低的烷基取代基,以及在苯二氮卓基团的4位和5位之间连接的杂环环。该杂环环将包含出现在苯二氮卓环的4位的氮原子,以及连接到苯二氮卓环5位的碳原子上的杂原子,该杂原子可能是氧或氮。“A”中带有新杂环环中的氧原子可以通过在酸催化剂存在下用环氧化合物处理相应的4,5-不饱和苯二氮卓制备而成。“A”中带有新杂环环中的氮或氧原子可以通过对应开放化合物的环化制备而成。“A”可用作镇静剂、肌肉松弛剂和抗惊厥剂。
