A chemoenzymic route to neuraminic acid 2 is described. This method is based on conversion of N-carbobenzoxymannosamine (ManCBz) 3 to N-carbobenzoxyneuraminic acid (Neu5CBz) 4, catalyzed by Neu5Ac aldolase. The Neu5CBz 4 was converted to the α-methyl glycoside 8 and deprotected to afford the free amine 2. This procedure has been scaled up to generate 10-gram quantities of 2. N-Acylation of 2 produced
