Abstract
Abstract Treatment of 2′,3′- O -isopropylideneuridine 5′-aldehyde with tributyltin hydride in the presence of azobisisobutyronitrile affords (6 S ,5′ S )-6,5′-cyclo-5,6-dihydro-2′,3′- O -isopropylideneuridine in a stereospecific manner. A similar reaction with N 6 -benzoyl-2′,3′- O -isopropylideneadenosine 5′-aldehyde leads to the corresponding 8,5′-cycloadenosine.
