Chalcones were synthesised in high purity and efficiency, via condensation of mono, bis and tris 2,4,6-trimethoxy acetophenones with hetero-2-carbaldehyde derivatives based on Claisen Schdmit condensation. The reactions feature a good scope for the all products, mild reaction conditions and good yields. The synthesized compounds were characterized by using FT-IR, NMR and elemental analysis spectroscopic techniques. © 2021 ACG Publication.
