Abstract

AbstractSyntheses of 2,3‐dimethyl‐4H‐furo[3,2‐c]coumarin and 3‐phenyl‐4H‐furo[3,2‐c]coumarin as angular furocoumarins were carried out through Williamson reaction of 4‐hydroxycoumarin with α‐haloketones followed by cyclization. Photooxygenation of the synthesized furocoumarin derivatives was performed and the photoproducts were isolated and characterized. The affinity of 2,3‐dimethyl‐4H‐furo[3,2‐c]coumarin towards DNA and the antibacterial activity were evaluated and compared with 8‐methoxypsoralen (8‐MOP).
