Cesium fluoride-mediated claisen rearrangements of phenyl propargyl ethers: substituent effects of an ortho-alkoxy group on the benzene ring or modified propargyl …
The expected 7-alkoxy-2-methylbenzo[b]furans were effectively given in the CsF-mediated Claisen rearrangement of phenyl propargyl ethers with an o-alkoxy substituent on the benzene ring. On the other hand CsF did not affect the production of the corresponding benzo[b]furans ...
