General description

3,5-Di-tert-butyl-2-hydroxybenzaldehyde undergoes condensation reaction with
  • methyl-2-{N-(2′-aminoethane)}-amino-1-cyclopentenedithiocarboxylate to yield Schiff base ligand
  • N,N-diethyl-2-methyl-1,4-phenylenediamine during the synthesis of copper(II) and cobalt(II) complexes of salicylaldimine

Application

3,5-Di-tert-butyl-2-hydroxybenzaldehyde was used in the synthesis of
  • Mn(III)-salen complex and its diamino precursor 5,6-diamino-5,6-dideoxy-1,2-O-isopropylidene-3-O-methyl-β-L-idofuranose
  • chiral Schiff base ligand for an enantioselective copper-catalyzed addition of phenylacetylene to imines
  • chiral oxazolidine ligand for the enantioselective addition of diethylzinc to aldehydes
  • tin Schiff base complexes with histidine analogues
