A series of 2‐(arylidene)‐indan‐1, 3‐diones 1 were prepared by Knoevenagel reaction between indane‐1,3‐dione and the appropriate araldehydes. The α,β‐enones 1 have been used as a component of Michael addition with equimolar amounts of 2‐aminopyridine/2‐aminopyrimidine to give novel heterocyclic systems 4 and 5, respectively. They are reported here for the first time. The structures of the newly synthesized
