Synthesis and biological evaluation of 5‐(1‐alkoxy‐2‐haloethyl)‐2′‐deoxyuridines and related uracil analogues

Abstract
A new class of 5‐[1‐alkoxy‐2‐iodo(or 2,2‐diiodo)ethyl] derivatives of 2′‐deoxyuridine and uracil were synthesized by a regiospecific reaction of the C‐5 vinyl substituent with iodine monochloride and an alcohol. These compounds were either weak or inactive antiviral and inactive cytotoxic agents.
