A new route to pyranocoumarins and their benzannulated derivatives

A new protocol based on sequential applications of three atom-economic processes viz. Claisen rearrangement, olefin isomerisation, and ring-closing diene metathesis has been developed to access a range of linear and angularly fused pyranocoumarin derivatives. Incorporation of enyne (in place of diene) metathesis and Diels-Alder reaction in the sequence has allowed the corresponding benzannulated derivatives to be prepared in good yields.

Synthesis of polycyclic coumarin derivatives by combined Claisen rearrangement, ring-closing metathesis, and Diels-Alder reaction

A new route to several hitherto unknown linearly and angularly architectured polycyclic coumarin derivatives has been developed involving tandem applications of three atom economic processes viz. Claisen rearrangement, ring-closing enyne metathesis, and D
