Claisen rearrangement of 7-propargyloxycoumarins: Formation of pyrano and furanocoumarins

The Claisen rearrangement of 4-methyl-7-propargyloxycoumarins in N,N-dimethylaniline results in the formation of angular pyranocoumarins (3) in high yields (71-78percent) and linear pyranocoumarins (4) in low yields (8-12percent).The effect of solvent on the rearrangement has been examined.
