First enantiospecific synthesis of dimorphecolic acid is accomplished via an efficient and stereocontrolled route. The convenient synthesis of 5(S)-HETE and 12(S)-HETE is also described.
A highly convergent totalstereocontrolledsynthesis of lipoxin B4 is described by an efficient Pd-catalyzed coupling reaction of two easily accessible chiral synthons 2 and 3 without any protection-deprotection sequence of the alcohol functions.
An efficient synthesis of (5S,12S)-diHETE was realized by a Pd-Cu catalysed coupling of the chiral synthons 3 and 4 which were easily obtained by the kinetic resolution of the corresponding racemates using the Sharpless reagent.
