Compositions for the treatment of cancer comprising coumarin and thiocoumarin derivatives of Formulas I- XII are disclosed. Said derivatives preferentially inhibit carbonic anhydrase IX and XII (which are associated with hypoxic and metastatic tumours) over inhibiting carbonic anhydrase I and II activity. The compositions therefore are suited for treatment of hypoxic or metastatic cancers due to this selective mechanism of action.

A new route involving a tandem Claisenrearrangement and ring-closing metathesis reaction has been developed for the synthesis of some hitherto unknown oxepin- and oxocin-annulated coumarin derivatives.
A synthetic strategy based on tandem application of Claisenrearrangement and intramolecular Heck reaction as key steps has been developed for the synthesis of various hitherto unknown benzoxocine- and benzoxonine-fused coumarin and quinolone derivatives.
