Abstract: A" chiral-pool" approach was employed to synthesize various leukotrienes (slow- reacting substance of anaphylaxis, SRS-A) enantiospecifically. The pivotal (S, S)-trans- epoxy alcohol 9 was prepared by efficient and facile routes starting from erythorbic acid (D- araboascorbic acid, 13). This epoxide could also be produced starting from D-glucose. The epimeric (S, R)-cis-epoxide 38 was obtained utilizing L-tartaric acid as the chiral starting ...
