The ammonium salt of 3-deoxy-D-manno-2-octulosonic acid (10) is synthesized from D-lyxose (2) via 1,2,3,4-tetra-O-acetyl-5-bromo-α-D-lyxopyranose (3) and radical C,C-bond formation with tert-butyl 2-(tributylstannylmethyl) propenoate (6). After deprotection and reduction, ozonolysis of 2,3-dideoxy-2-methylene -D-manno-octonic acid (9) yields the target molecule 10.
