Sialic acids are accessible synthetically by chain extension of 2-acetamido-2deoxy-D-glucose or -D-mannose with oxaloacetate'. However, due to epimerisation at C-2 under alkaline conditions, mixtures of four products are formed, the fractionation of which is sometimes difficult. The aldehydo-2-acet
The effect of trifluoroacetylation on the 13C chemical shifts of 2-acetamido-2-deoxyhexoses was examined. Studies of the 2-acetamido derivatives of glucose, galactose and mannose established that no regular trend in the 13C shifts occwred on tduoroacetylation. This was in marked contrast to the resu
