Alicyclic 1,5,9-triketones with various combination of 5-, 6-, 7-membereded cycles in the molecule were obtained by methods of diketone condensation, Michael reaction, and proceeding from Mannich mono- and bisbases and cycloalkanones. The latter method was accompanied with a transaminomethylation, observed for the first time at triketones preparation. The structures of cyclic forms of Michael reaction

New tetracyclic dispiro-1,2,4-trioxolanes (ozonides) were synthesized by reactions of 5–7-membered alicyclic 1,5-diketones with 30% hydrogen peroxide in diethyl ether or ethanol in the presence of borontrifluoride-diethylether complex or a strong mineral acid (HCl, H2SO4, HClO4). Mass spectrometric study of the title compounds under atmospheric pressure chemical ionization revealed specificity of
在三氟化硼-乙醚复合物存在下,通过5-7元脂环族1,5-二酮与30%过氧化氢在乙醚或乙醇中的反应,合成了新的四环二螺1,2,4-三氧杂环戊烷(臭氧化物)或强无机酸(HCl,H 2 SO 4,HClO 4)。标题化合物在大气压化学电离下的质谱研究表明,碎片离子分解相对于环的大小具有特异性,这使得可以通过质谱鉴定这类化合物。

The invention relates to novel 5,6,7,8-tetrahydroquinoline derivatives which have a group X situated at the 8-position said group X is CONHR.sup.3, or CO.sub.2 R.sup.5 wherein R.sup.3 is hydrogen lower alkyl and R.sup.5 is hydrogen, lower alkyl or a lower aralkyl radical. The compounds are intermediates for corresponding compounds where X is CSNHR.sup.3 and these are anti-ulcer agents.
The invention relates to novel 8-cyano-5,6,7,8-tetrahydroquinoline derivatives which are intermediates for the preparation of corresponding 8-thioamides. Some of the 8-cyano compounds are anti-ulcer agents.
