Synthesis of 2′-Deoxy-6,2′-Ethano-Cyclouridine1(Nucleosides and Nucleotides. Part 57)

Abstract
Synthesis of a carbon-bridged cyclouridine,2′-deoxy-6,2′-ethano-cyclouridine, was accomplished starting from a 2′-ketouridine via the 2′-deoxy-2′-iodoethyl-5-chlorouridine derivative through a radical cyclization.
