Pictet–Spengler reaction Pictet–Spengler reaction The Pictet–Spengler reaction is a chemical reaction in which a β-arylethylamine undergoes condensation with an aldehyde or ketone followed by ring closure. The reaction was first discovered in 1911 by Amé Pictet and Theodor Spengler. Traditionally an acidic catalyst in protic solvent was employed with heating, however the reaction has been shown to work in aprotic media without acid catalysis in superior yields for a variety of cases. The Pictet–Spengler reaction can be considered a special case of the Mannich reaction, which follows a similar reaction pathway. The driving force for this reaction is the electrophilicity of the
