A series of fused dihydrooxepino[h]and dihydrooxepino[g]coumarins (7 and 8) were synthesized through allylation, Claisenrearrangement, allylation and ring-closing metathesis (RCM), respectively. All the synthesized compounds were characterized by appropriate spectral analysis. The anti-proliferative activities of compound 5a-c, 6a, 6c, 7a-c and 8a-c were evaluated against human colon cancer (Caco-2)
