9-N-acyl-5-trifluoroacetyl methyl alpha-ketosides (1a-c) and their 2,3-didehydro analogs (2a-c) have been synthesized through Neu5Ac aldolase-catalyzed aldol reaction of 6-azido-2-benzyloxycarbonylamino-2-deoxy-D-mannose with sodium pyruvate. The six compounds were investigated as inhibitors of sialidase from influenza virus. Compound 2b, a 2,3-didehydro type, showed the most potent inhibitory activity
