Methanolysis of methylated hyaluronic acid, followed by acetylation, gave, in 70% yield, crystalline methyl 2-acetamido-2-deoxy-4,6-di-O-methyl-3-O-(methyl 4-O-acetyl-2,3-di-O-methyl-beta-D-glucopyranosyluronate) -alpha-D-glucopyranoside. Removal of the O-acetyl and methyl ester groups gave compounds that are useful in the investigation, by 1H-n.m.r. spectroscopy, of interaction within chains of hyaluronic
甲基化透明质酸的甲醇分解,然后乙酰化,以70%的收率得到结晶的甲基2-乙酰氨基-2-脱氧-4,6-二-O-甲基-3-O-(甲基4-O-乙酰基-2 ,3-二-O-甲基-β-D-吡喃葡萄糖苷)-α-D-吡喃葡萄糖苷。除去O-乙酰基和甲基酯基团得到的化合物可用于通过1H-nmr光谱研究溶液中透明质酸链内的相互作用。
