A stereoselective totalsynthesis of (11R,12S)-diHETE is described. The strategy is based on the use of a 'sugar' derived 'chiron' for the incorporation of 'vic-diol' stereocentres, while Wittig reactions for the assembly of requisite carbon frame work of the target molecule.
The first total synthesis of (11R,12S) diHETE is reported. The key step is the highly chemio- and stereoselective osmylation of a double bond in a trienyne system selectively complexed by an Fe(CO)3 group.
