Abstract: Novel Furan-ring Fused Chalcones (FFC) were synthesized using a radical cyclization reaction
of α,β-unsaturated ketones with cyclic ketone as the model reaction to attain this goal. In this study,
traditional and microwave-assisted methods for the efficient and cost-effective synthesis of furan-ring
fused chalcones in mild reaction conditions are compared and optimized. The goal is to develop a reliable
and adaptable synthetic technique that may be used to produce these useful chalcone derivatives
quickly and effectively. The optimal experimental conditions for these reactions were carefully determined
using two independent methodologies: conventional (Method A) and microwave (Method B).
The results indicated that the proposed method B could be used effectively in the future to synthesize
novel furans with short reaction times and acceptable yields (87-94 %), and products were purified by
column chromatography and preparative thin layer chromatography (PTLC). All new compounds were
characterized by 1H-NMR, 13C-NMR, LC-MS, and elemental analyses.
