Synthesis and Biological Properties of ( ) and (-)-(E)-5-(2-bronovinyl)-21 -deoxy-11 a-Carbauridine

Abstract

Carbocyclic (+)- and (-)-(E)-5- (2-bromovinyl)-2′-deoxyuridlne have been prepared from (+)- and (-)-endo-norborn-5-en-2-y1 butyrate. In cell cultures both (+)- and (-)-C-BVDU showed activity against herpes simplex virus types 1 and 2, (+)-C-BVDU being only slightly less active than BVDU itself. (-)-C-BVDU gave a smaller but still significant antiviral effect. A nomenclature for carbocyclic nucleosides is proposed.
