Oxazolidinone glucosamine

The oxazolidinone protected A -acetyl glucosamine 4-OH derivative 221 exhibited enhanced reactivity as a glycosyl acceptor in a variety of coupling methods. The products were finally converted to the target A -acetylglucosaminyl saccharides under very mild conditions <03OL1297>.

This year has again seen several synthetic routes to sphingosines and analogues. Oxazolidinone 312 was converted by the same workers to o-erythro-sphingosine 319 in six steps and JV-benzoyl glucosamine has also been elabo-...
