Synthesis of the bicyclic core of the nucleoside antibiotic octosyl acid A

The bicyclic core of octosyl acid A has been prepared using a diastereoselective acetylide addition and 6-endo selenoetherification as key steps. A detailed study of the selenoetherification reaction and difficulties encountered in the conversion of a phe
