AN ENANTIOCONVERGENT ROUTE TO CARBOCYCLIC NUCLEOSIDES (-)-ARISTEROMYCIN AND (-)-NEPLANOCIN A VIA THE ASYMMETRIC DIELS-ALDER REACTION

The asymmetric Diels-Alder reaction of (SS)-menthyl-3-(2-pyridylsulphinyl)acrylate (4) with cyclopentadiene gave almost a pure single diastereoisomeric cycloadduct.The cycloadduct was then converted into the central intermediate (+)-(3) which w
