Application

Protecting reagent for amines, alcohols, and thiols.
Trityl chloride can be used as a catalyst:
  • In Ritter type synthesis of 1-amidoalkyl-2-naphtols through a one-pot three-component reaction of naphthol, aryl aldehydes and acetonitrile.
  • In the synthesis of 1,2,4,5-tetrasubstituted imidazoles via a one-pot multi-component reaction of benzil with aldehydes, primary amines, and ammonium acetate.
  • In the preparation of amido alkyl phenols via one-pot, multi-component reaction of phenols, aromatic aldehydes, and amides under solvent-free conditions.
  • In one-pot, multi-component synthesis of substituted piperidines using aromatic aldehydes, amines, and β-ketoesters.
