General description

Benzyloxyacetaldehyde is a non-natural aldehyde. It undergoes enantioselective Mukaiyama aldol reaction with silylketene acetal nucleophiles in the presence of C2-symmetric bis(oxazolinyl)pyridine Cu(II) complex (catalyst).

Application

Benzyloxyacetaldehyde may be used in the following syntheses:
  • (3S,5S)-methyl 6-benzyloxy-3,5-dihydroxyhexanoate
  • (S)-5-benzyloxy-4-hydroxypentan-2-one
  • myxothiazols
Benzyloxyacetaldehyde may be used in the synthesis of 1-deoxy-L-xylulose, via antibody catalysis.
