Ethyl 5-O-(2'-tetrahydropyranyl)-2, 3-anhydro-β-DL-lyxofuranoside (VIDL) was predominantly formed by the action of alkali on a chlorohydrin derivative, which was prepared by hypochlorous acid addition of 2'-ethoxy-5-(2'-tetrahydropyranyloxy) methyl-2, 5-dihydrofuran (I). Then, ethyl 3-amino-3-deoxy-β-DL-arabinofuranoside (IXDL) was synthesized from VIDL.
