6-Epi-leukotrienes C and D (3 and 4) have been synthesized unambiguously via the 5(S), 6(R)-epoxide (5,6-cis) which is isomeric with leukotriene A. These 6-epi-leukotrienes are less active (especially 4) than leukotrienes C and D (1 and 2) and have not been found in substantial quantity in natural SRS sources.
