A series of 2,4,6-triarylpyridines have been prepared using a variety of aromatic and heteroaromatic aldehydes in the presence of aluminum phosphate (AlPO4) as a heterogeneous catalyst at 120 oC under solvent-free conditions. The present methodology offers several advantages such as excellent yields, simple procedure, shorter reaction times, milder conditions and the catalyst exhibited remarkable reusable activity. Keywords: Aluminum phosphate; 2,4,6-triarylpyridines; One-pot synthesis; Shorter reaction times;  Reusable activity.  © 2010 JSR Publications.

Solvent Free Synthesis

: An efficient four-component reaction to synthesize pyrrolo[2,1-a]isoquinolines from malononitrile, aromatic aldehydes, isoquinoline, and cyclohexyl isocyanide under solvent-free conditions is described. In a convenient, simple, and efficient one-pot procedure, the domino Knoevenagel-nucleophilic cycloaddition reaction affords excellent yields of products in less than 1 h.
