A number of new linearly fused furochromones were synthesized. The methodology was performed starting from naturally occurring visnagin and khellin via enaminone formation using N,N-dimethyl formamide dimethylacetal followed by ring closure in acidic medium. Various reactions on the enaminone derivatives are described.
