The tritylation of methylα- and β-D-xylopyranoside afforded three isomeric trityl ethers in both cases. All the ethers were separated by column chromatography in almost pure forms on TLC. Among them, methyl 2-O-trityl-α- and methyl 3-O-trityl-β-D-xylopyranoside were crystallized from aqueous ethanol. The position of the trityl group in each ether was mainly established by the use of 1H NMR with its
