Asymmetric Synthesis of a Chiral Building Block for Cyclopentanoids: A Novel Enantioselective Synthesis of Preclavulone A

Stereoselective preparation of key intermediates for the synthesis of iso-, neuro- and phyto-prostane family members: inaugural asymmetric synthesis of 17-E2c-dihomo- and 17-F2c-dihomo-isoprostanes

A practical methodology for the synthesis of key intermediates for isoprostane, neuroprostane and dihomo-isoprostane preparation has been described. The key strategy involved a three stage C-12 stereocenter inversion of the configuration of a Corey lactone, commercially available in an enantiopure form. The key intermediate was then used to prepare 17-E2c-dihomo-isoprostane and 17-F2c-dihomo-isoprostane.

A unified stereodivergent strategy for prostaglandin and isoprostanoid synthesis

Acetoxyfulvene surrended to asymmetric Diels-Alder cycloaddition, paving the way to the development of a unified strategy for the stereodivergent synthesis of both prostaglandins and isoprostanoids. In fact, the cycloadduct was subsequently converted to a common intermediate, which through two different stereoselective pathways afforded the two lactones 1 and 2, which are key building blocks in the synthesis of prostaglandins and isoprostanoids, respectively.

A New Approach to the Synthesis of Chiral Blocks for Cyclopentanoids

A microreview is presented of the development by the authors of the original preparation of enantiomerically pure cyclopentane blocks from the racemic [2+2]-cycloadducts of 1,3-cyclopentadiene and its derivatives with dichloroketene.
