摘要
通过 N-苯基马来酰亚胺与 7-取代的环庚烷-1,3,5-三烯的环加成反应，可以得到新的 4-氮杂四环[5.3.2.02,6.08,10]十二-11-烯-3,5-二酮，收率高达 87-97%。发生[4 + 2]环加成反应的真正底物是 7-R-双环[4.1.0]庚-2,4-二烯同系物。核磁共振光谱和 X 射线衍射分析证明了合成化合物的结构。
New 4-azatetracyclo[5.3.2.02,6.08,10]dodec-11-ene-3,5-diones via the cycloaddition of N-phenylmaleimide and cyclohepta-1,3,5-trienes
The cycloaddition reactions of N-phenylmaleimide with 7-substituted cyclohepta-1,3,5-trienes afforded new 4-aza- tetracyclo[5.3.2.02,6.08,10]dodec-11-ene-3,5-diones in high yields (87–97%). The true substrates which underwent the [4 + 2] cycloaddition were the 7-R-bicyclo[4.1.0]hepta-2,4-diene tautomers. The structures of the synthesized compounds were proved by NMR spectroscopy and X-ray diffraction analysis.
期刊介绍：
Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications.
Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
