Epoxidation of trans-6-ethoxy-5-hydroxy-5,6-dihydro-2H-pyran (3) provides ethyl 3,4-anhydro-β-DL-ribopyranoside (5).Compound 5 in turn affords ethyl α-DL-lyxopyranoside (6) as a major product when the epoxide ring is opened either by hydroxide ion or by water in the presence of an acid catalyst.Reaction of osmium tetroxide with 3 yields ethyl α-DL-arabinopyranoside as principal product which has been identified as its 2,3,4-tri-O-acetyl derivative (8).
