Stereocontrolled total synthesis of leukotriene B4
摘要:
A stereocontrolled synthesis of leukotriene B4 (1) is accomplished by assembly of the chiral synthons 2 and 4, prepared from D-mannitol and 2-deoxy-D-ribose, with (E)-dichloroethylene.

Optically active α-hydroxy and α,β-dihydroxyaldehydes, usefulintermediates for synthesis of lipoxygenase metabolites of arachidonicacid, are synthesized highly diastereoselectively starting with readily available D-glyceraldehyde acetonide.
The Pd-Cu coupling reaction of a chiral hydroxy-(E,E)-iododiene with a racemic acetylenic alcohol followed by reduction of the dienyne leads to the desired (Z,E,E) geometry and allows synthesis of LTB4 and its 5-epimer after separation of diastereomers.
