A new synthesis of the 1-C~6-C fragment Et 5(S)-(benzoyloxy)-6-oxo-hexanoate (I) and the 11-C~20-C fragment 2(R)-(tert-butyldiphenylsiloxy)dec-4(z)-enal (II) of LTB4 utilizing D-mannitol and L-ascorbic acid as the chiral pool is described resp. The stereoselective addition reaction of the chiral 2,3-O-isopropylidene-glyceraldehyde with propargyl bromide in presence of zinc powder is a key step.
