An Improved Synthesis of 3-(1,1-Dimethylallyl)coumarins

The syntheses of several 3-(1,1-dimethylallyl)coumarins, simple or bearing additional furan or pyran rings is achieved starting from the corresponding C-3 unsubstituted derivatives.The key step involves Ireland-Claisen rearrangements of allyl esters.

Synthesis of 3-(1,1-Dimethylallyl)xanthyletin, 3-(1,1-Dimethylallyl)-8-(3,3-dimethylallyl)xanthyletin, Gravelliferone and dl-Chalepin

The synthesis of title compounds has been achieved from the key intermediate 3-(1,1-dimethylallyl)-7-hydroxycoumarin (7) which, in turn, is obtained by triple Claisen rearrangement of 7-(3,3-dimethylallyl)oxycoumarin (2) using butyric anhydride as the trapping reagent.
