A stereocontrolled total synthesis of six lipoxin B isomers are described. The flexible and stereoselective strategy involves Sharpless asymmetic epoxidation and pinylborane asymmetic reduction to secure the three hydroxyl-bearing stereocenters and a Wittig-type as well as palladium(0)-copper(I) coupling reactions to construct the carbon skeleton of the target molecules.

Chiral 1,2-epoxy-3-alkanol tosylates were successfully synthesized from alkynols in three steps using the Sharpless AD reaction as a key step in good yields. Two chiral insect pheromone epoxides were smoothly obtained from the corresponding key intermediate. (C) 1999 Elsevier Science Ltd. All rig;hts reserved.
