Synthesis of 1-O-R-5-deoxy-β-D-ribofuran

Synthesis of 1-O-R-5-deoxy-β-D-ribofuranosides with (CH3)2As and (CH3)2AsO as substituents at the 5-position and a methyl or 2′,3′-dihydroxypropyl group as the aglycone in the 1-position

including the naturally occurring (2'R)dimethyl[ l-O-(2',3'-dihydroxypropyl)-5-deoxy-~-~-ribofuranos-5-yl]arsine oxide, were prepared in multi-step reactions from D-ribose and tetramethyldiarsine. The synthetic procedure uses the early substitution of the hydroxy group with bromine at C5, subsequent
