3-d]-Δ2′-oxazoline (XXI) are described. The reduction product was a derivative of 2-amino-2-deoxy-D-allitol, indicating that no isomerisation of the sugar system in compound (XXI) had occurred during its formation and reduction. A derivative of muramic acid containing a reduced side chain was synthesised from a phenyloxazoline derivative of 2-amino-2-deoxy-D-glucofuranose. A convenient method for the preparation
