Two epoxy alcohols, 11,12-epoxy-15-hydroxy-5,8,13-eicosatrienoic acid and 13,14-epoxy-15-hydroxy-5,8,11-eicosatrienoic acid, were recently isolated following incubation of arachidonic acid with homogenates of the fungus, Saprolegnia parasitica (Hamberg, M., Herman, C.A. and Herman, R.P. (1986) Biochim. Biophys. Acta 877, 447-457). In the present study the complete stereochemical structures of the two epoxy alcohols were determined by steric analysis of short chain acids formed by chemical degradation and by NMR-spectrometric analysis. The epoxy alcohols were found to be 11(S),12(R)-epoxy-15(S)-hydroxy-5(Z),8(Z),13(E)-eicosatrienoic acid and 13(R),14(R)-epoxy-15(S)-hydroxy-5(Z),8(Z),11(Z)-eicosatrienoic acid.
