[GRAPHICS]Radical cyclization of the beta-alkoxymethacrylate obtained from 5-benzyloxy-1-iodohexan-3-ol led to the stereoselective preparation of the benzyl ether of (+)-methyl nonactate, demonstrating "2,5-cis" selectivity in the radical cyclization step in forming a tetrahydrofuran ring system and "threo" selectivity in the hydrogen abstraction step.
