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