Various 1,3‐dimethyl and 1‐methyl‐3‐phenylfuro[3,4‐ c ]coumarins ( 5a‐h and 6a‐h ) have been synthesized by demethylation cyclization of the respective 3‐aryl‐4‐ethoxycarbonyl furans ( 3a‐h and 4a‐h ). These ethoxycarbonyl furans were prepared by reacting appropriate 1‐aryl‐2‐nitro‐prop‐1‐ene ( 1a‐h ) with ethyl acetoacetate or ethyl benzoylacetate under Nef reaction condition.
