Abstract

Trichloroacetic Acid (TCA) was used as an efficient catalyst for the synthesis of highly
functionalized piperidines via a one-pot five-component reaction of aromatic amines, aromatic
aldehydes and β-keto esters in MeOH at room temperature. The remarkable advantages
offered by this method are good yields, simple procedure, short reaction times, no need to
column chromatography and an easy work-up.
