3-O-ETHERS of D-glucosamine, including muramic acid (3-O-carboxyethyl-D-glucosamine, a component of bacterial cells walls), have been prepared1–4 from the intermediate I (R = Me or Et)5. We have applied the Williamson ether synthesis to the intermediate II (R = H)6 and have prepared muramic acid, 3-O-methyl- and 3-O-carboxymethyl-D-glucos-amines by this procedure. The intermediate (II) is readily prepared in good yield by a two-stage process, whereas the preparation of substance I requires three steps and a separation of the α and β anomers7,8.
