Arene Oxides of Quinoline: Epoxidation, N-Oxidation and N-Methylation Reactions

trans-5,6,7,8-Diepoxy-5,6,7,8-tetrahydroquinoline 5, 5,6-epoxy-5,6-dihydroquinoline 1-oxide 3, 7,8-epoxy-7,8-dihydroquinoline 1-oxide 4 and trans-5,6,7,8-diepoxy-5,6,7,8-tetrahydroquinoline 6 have been formed by oxidation of the corresponding arene oxides of quinoline, 5,6-epoxy-5,6-dihydroquinoline 1 and 7,8-epoxy-7,8-dihydroquinoline 2.The cis-diepoxides, cis-5,6,7,8-diepoxy-5,6,7,8-tetrahydroquinoline 8 and cis-5,6,7,8-diepoxy-5,6,7,8-tetrahydroquinoline 1-oxide 9 were both obtained by a stepwise synthesis from 7,8-epoxy-7,8-dihydroquinoline 2 via the bromohydrin 7.N-Methylation of 5,6-epoxy-5,6-dihydroquinoline 1 and 7,8-epoxy-7,8-dihydroquinoline 2 with methyl trifluoromethanesulfonate yielded the corresponding N-methylquinolinium arene oxide salts 10 and 11.
