概要

• 論文の詳細を見る

• The tritylation of methyl α- 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-<I>O</I>-trityl-α- and methyl 3-<I>O</I>-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 <SUP>1</SUP>H NMR with its diacetyl derivative.
