  First Enantioselective Total Synthesis of (8S,12R,15S)-Prostaglandin J₂

  摘要：

  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.

  A practical methodology for the synthesis of J-type prostaglandins has been developed starting from the well-consolidated approaches established for the synthesis of A-type prostaglandins. An efficient 1,3-allylic transposition of the C-9 hydroxyl group of intermediate 4 furnished the advanced precursor 5 for J(2) synthesis. Our optimized A-J swap protocol employed selenium chemistry, involving the [2,3] sigmatropic rearrangement of secondary allylic selenoxide 11a.
