中文摘要：

α-四氢萘酮的乙氧羰基腙（1）经LTA氧化，得到α-偶氮-α-乙酰氧基化合物2．在AlCl3作用下，化合物2脱去乙酰氧基产生重氮正离子中间体3，再经与腈的1，3-偶极环加成、[1，2]-迁移扩环、碱性水解和与苦味酸作用，得到新型[1，2，4]-三唑并[1，5-a][1]苯并氮杂[艹卓]苦味酸盐6a-6c．以2，3-二氢-1-茚酮为底物，采用相同的合成路线，合成了1，2，4-三唑并[1，5-a]-二氢喹啉苦味酸盐12a-12c。

英文摘要：

Oxidation of α-tetralone ethoxycarbonylhydrazone （1） with lead tetraacetate afforded the bicyclic geminal ethyl azoester 2. On addition of equimolecular aluminum trichloride, the azocarbenium salt 3 was generated in situ as a reactive intermediate, which could be trapped by the cycloadditions to the triple bonds of ni- triles giving 3H-1,2,4-triazolium salts. These initially cycloadducts couldn＇t be isolated but underwent smooth 1,2-aryl-shift with concurrent ring enlargement and insertion of a nitrogen atom to the carbon skeleton to provide the tficyclic salts 4a--4c, from which the literature unprecedentate [ 1,2,4 ] triazolo [ 1,5-a ] [ 1 ] benzazepinium picrates 6a--6c were obtained in 23% - 56% yields upon hydrolytic removal of the N-ethoxycarbonyl group and subsequent treatment of the resulted heterocycles 5 with picric acid. Analogously, the novel 4,5-di- hydro- [ 1,2,4 ] triazolo [ 1,5-a ] quinolinium picrates （ 12a--12c ） were prepared from 2,3-dihydro-1 -indanone in moderate yields.
