ChemInform Abstract
The multi-step reaction sequence described provides a viable route for the preparation of multigram quantities of arsenic-containing ribofuranosides such as (IV) and (VIII) starting with the inexpensive D-ribose (I) and employing tetramethyldiarsine (III). Dimethyl(ribosyl) arsine oxides are the major arsenic compounds from marine algae species.
