[4+2] Cycloaddition reaction of 1-(cyclopenten-1-y1)-1-morpholino ethene with β-nitrostyrene leads to tetrahydroindan and tetrahydroindanone derivatives. A [4+2] adduct of interest is also obtained in the reaction of the same substrate with mesyl chloride. Reactivity of the same electrophiles with the morpholino enamine of cyclopentyl-methyl ketone is also examined. Some stereochemical aspects of the
[4 + 2] 1-(环戊烯-1-y1)-1-吗啉代乙烯与β-硝基苯乙烯的环加成反应生成四氢茚满和四氢茚满酮衍生物。在相同底物与甲磺酰氯的反应中也获得了感兴趣的[4 + 2]加合物。还检查了相同的亲电试剂与环戊基甲基酮的吗啉代烯胺的反应性。讨论了上述反应的一些立体化学方面。
