Enantioselective synthesis of natural PGJ(2) has been accomplished for the first time starting from the commercially available enantiopure aldehyde 7 in 10% overall yield. The key reaction was a novel prostaglandin class interconversion, i.e., an allylic 1,3-transposition across alcohol 9 derived from compound 14 in 73% overall yield. In principle, the unnatural enantiomer of PGJ(2) could be obtained starting from the commercially available enantiopure monobenzoate 7a following our strategy.
