Total synthesis of (+)-Leukotriene B4 methyl ester and its 5-epimer from (R)-glycidol
摘要:
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.
