Abstract
An aldol reaction between the divalent tin enol ether of racemic N -Boc α-aminodienone-tricarbonyliron
complex and multiprotected d -glyceraldehyde
provided predominantly two enantiomerically pure ketol diastereoisomers.
From there, multiprotected kanosamine and 3-amino-3-deoxy-d -altrose were obtained in a few high-yielding
steps, namely stereoselective reduction, protection, decomplexation,
and ozonolysis.
Key words
α-aminodienone-tricarbonyliron complexes - divalent tin enol ether - aldol reactions - kanosamine - amino sugars
