A novel and direct synthesis of hydroperoxy compounds from various types of conjugated olefins was established via cobalt(II) porphyrin-catalyzed hydroperoxygenation. The reaction of α,β,γ,δ-unsaturated carbonyl compounds, acrylic esters, α-substituted acrylic esters and styrene derivatives with molecular oxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) porphyrin proceeded rapidly to give the corresponding hydroperoxygenated compounds in high or moderate yields.

Various olefins such as styrenes, α,β-unsaturated carbonyl compounds, and α,β,γ,δ-unsaturated carbonyl compounds were directly converted to the corresponding acetophenoximes, α-hydroxyimino carbonyl compounds and γ-hydroxyimino-α,β-unsaturated carbonyl compounds in good or moderate yields by reduction-nitrosation with t-butyl nitrite and triethylsilane in the presence of cobalt(II) porphyrin as a catalyst.

Derivatives of (11E)-10-oxo-11-octadecen-13-olide (1) and its seco-acid 2 were synthesized from linoleic acid for purpose of elucidation of their cytotoxic activity. Linoleic acid was converted to (13S, 9Z, 11E)-13-hydroxy-9,11-dienoic acid (4) by soybean lipoxygenase-catalyzed oxidation followed by treatment with NaBH_4. The hydroxy acid 4 was cyclized by the Yamaguchi method and by the Mitsunobu method, to give 14-membered lactones S-5 and R-5, respectively, which reacted with oxygen and triethylsilane in the presence of Co(tdcpp) as a catalyst followed by acetylation-decomposition of the intermediary hydroperoxide to produce S-1 and R-1. Lipase-catalyzed hydrolysis of R-1 gave hydroxyketo acid R-2. The reduction-oxygenation of dienoic ester 7, prepared from 4 by treating with diazomethane and then t-butyldimethylsilyl chloride, afforded oxo derivative 8, which was deprotected to give hydroxyketo acid S-2. The other derivatives related to 1 and 2 were also synthesized by the similar manner described above. On the other hand, (E)-4-hydroxy-2-nonenal (HNE) and (E)-4-hydroxy-2-hexenal (HHE), cytotoxic aldehydes produced during lipid peroxidation in biological system, were synthesized in one step from commercially available 2,4-alkadienals by the Co(tdcpp)-catalyzed reduction-oxygenation. The deuterium-labeled HNE and HHE were prepared by use of triethyldeuterosilane and 2-propan(old) instead of triethylsilane and 2-propanol on the reduction-oxygenation of 2,4-alkadienals. The IC_<50> values of the fatty acid derivatives were determined against P388 mouse leukemia cells. The macrolide 1 showed the strongest cytotoxicity among the derivatives, however, no difference in the cytotoxicity was found between the optically active and racemic forms of 1. The cytotoxicity of the macrolides was enhanced, respectively, in comparison with that of the corresponding seco-acids. The enone moiety of 1 and 2 is assumed to be important for enhancing the cytotoxic action.

Both the S and R enantiomers of (E)-13-hydroxy-10-oxo-11-octadecenoic acid (1) and (E)-10-oxo-11-octadecen-13-olide (2) had similar IC50values against P388 mouse leukemia cells; i.e. the stereochemistry of the asymmetric center of 1 and 2 had no influence on the cytotoxic activity. Bioassay results of various compounds related to 1 and 2 suggests that the 10-oxo and lactone moieties of 2 were important for enhancing the cytotoxicity. © 1998, Taylor & Francis Group, LLC.
