A facile onepot transformation of BaylisHillmanacetates to pyrido[1,2‐a]pyrimidin‐2‐ones by reaction with 2‐amino pyridine in a total solvent‐free protocol is illustrated. The 3‐substituted‐2H‐pyrido[1,2‐a]pyrimidin‐2‐ones are obtained in pure form without involving any purification technique or solvent. J. Heterocyclic Chem., (2011).
