摘要
A new organocatalytic process of cyclotrimerization of the aliphatic and aromatic acetylenic ketones was developed. The reaction catalyzed by DMAP in the presence of 2,4-pentanedione gave 1,3,5-trisubstituted benzenes in almost quantitative yields under very mild conditions. 2,4-Pentanedione was used as a cocatalyst to promote the reaction efficiently, particularly for aliphatic acetylenic ketones.
