N2 - The four stereoisomers 11,12,15(S)-THETA were prepared by a triply convergent, asymmetric route that exploited the stereospecific, copper mediated cross-coupling of α,β-dialkoxystannanes and the utility of dialkylthionocarbamates as orthogonal alcohol protective groups. Only 11(R),12(S),15(S)-THETA was comparable to natural material by HPLC, GC/MS, and in vitro bioassay. The four stereoisomers of the endothelial-derived vasorelaxant 11,12,15(S)-trihydroxyeicosatrienoic acid [1, 11,12,15(S)-THETA] were prepared by a triply convergent, asymmetric route that exploited the stereospecific, copper mediated cross-coupling of α,β- dialkoxystannanes with organic electrophiles and the utility of dialkylthionocarbamates as orthogonal alcohol protective groups. Only 11(R),12(S),15(S)-THETA was comparable to natural material by HPLC, GC/MS, and in vitro bioassay.
