Lithium aluminium deuteride (LAD) promoted ring-opening reactions of appropriately protected methyl 2,3-anhydro-α-D-ribofuranoside and methyl 2,3-anhydro-β-D-lyxofuranoside , gave 2-deoxy-2()-deuterio--pentose and 2-deoxy-2()--pentose derivatives, and , respectively. Compounds and were subsequently converted to 2-deoxy-2(S)-deuterio- and 2-deoxy-2()-deuterio--pentofuranosyl chlorides, and respectively
