Stereoselective conjugate addition of nitrogen and carbon nucleophiles to sugar-derived enones: Synthesis of sialic acid analogues

The conjugate addition of benzylamine to three polyalkoxy ?±,?2-enones derived from D-glyceraldehyde, D-erythrose, and D-mannose, whose carbonyls were flanked by the thiazole ring, proceeded with modest to good synselectivity. The resulting polyalkoxy ?2-

Synthesis of a sialic acid analog with the acetamido group at C-4

An isomer of N-acetylneuraminic acid (Neu5Ac) with the acetamido group at C-4 (iso-Neu4Ac) has been synthesized through stereoselective 1,4-conjugate addition of trimethylsilyl azide to a 2-thiazolyl α,β-enone bearing a protected D-mannose moiety at C-β.
