A series of novel spiroadamantyl- and spirocyclical substituted pyranoquinolin-2-ones were synthesized and the conformation of the pyran ring was investigated. The free radical scavenging activity of the synthesized compounds was determined by their interaction with the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). All compounds tested scavenged the DPPH radical and among them derivatives possessing extended conjugation showed the highest activity.
一系列新型螺金刚烷基和螺环取代吡喃喹啉-2-酮被合成,并对吡喃环的构象进行了研究。合成化合物的自由基清除活性通过它们与稳定的自由基1,1-二苯基-2-苦基肼(DPPH)的相互作用来确定。所有测试的化合物都能清除DPPH自由基,其中具有扩展共轭的衍生物表现出最高的活性。
