The first total and enantioselective synthesis of 11-R,12-R-dihydroxy-5,8,14-eicosatrienoic acid is reported. We have used the carbohydrate 2-deoxy-D-glucose as a masked 1,6-dialdehyde precursor to perform the synthesis. The availability of this material will allow, among other things, the testing of the hypothesis that it can be a biochemical precursor to 12-R-HETE in vivo. ... The first total and enantioselective synthesis of title compound has been ...
