dietherate into epoxy alcohols and chloroepoxides, catalytic amounts of copper(II) trifluoromethanesulphonate in the presence of octanoic acid under oxygen efficiently convert the second compound into hydroperoxy dioxolanes and dioxabicycloheptanes, and methyl (5Z,8Z,11Z,13E,15S)-15-hydroperoxyeicosa-5,8,11,13-tetraenoate (15-HPETE methyl ester, 18) into hydroperoxy bisdioxolanes via an 11-peroxy radical
而甲基(9 Z,11 E,13 S)-13-hydroperoxyoctadeca-9,11-dinoate(3)和甲基(9 Z,11 E,13 S,15 Z)-13-hydroperoxyoctadeca-9,11,15 -三烯酸酯(4)被FeCl 3二醚酸酯转化为环氧醇和氯环氧化物,催化量的三氟甲磺酸铜(II)在辛酸的存在下,在氧气下有效地将第二种化合物转化为氢过氧二氧戊环和二氧杂双环庚烷,以及甲基(5 Z, 8 Z,11 Z,13 E,15S)-15-氢过氧双酚-5,8,11,13-四烯酸酯(15-HPETE甲酯,18)通过11-过氧自由基变成氢过氧双二氧戊环。
