  Total Synthesis of 15-D_2t- and 15-epi-15-E_2t-Isoprostanes

  摘要：

  The first total synthesis of 15-D-2t-isoprostane is described. (-)-(9S, 15S)-15-D-2t-IsoP 1 and (+)-(11R, 15R)-15-epi-15-E-2t-IsoP 2 have been obtained in 15 steps from orthogonally protected enantiopure bicycle 3. Key features include an easy introduction of the cis side chains via ozonolysis, a highly selective enzymatic chemical differentiation of a non-meso-1,5-diol, and the use of a common synthetic intermediate allowing a stereodivergent approach to the target molecules.
