A new approach to the synthesis of the 6H-benzo[d]naphtha[1,2-b]pyran-6-one ring system present in the gilvocarcin family of antibiotics is described. The key feature of this approach is the application of a new benzannulation strategy (the 'BHQ Reaction'

Allyl, crotyl, methallyl and cinamyl ethers of 4-hydroxy-, 7-hydroxy-, and 4-methyl-7-hydroxycoumarins have been efficiently synthesized and rearranged to substituted allylcoumarins under microwave irradiation. Irradiation of allylcoumarins in the presence of BF3/ether directly produced substituted dihydrofurocoumarins in good yields.
