Problems solved by technology

The activation energy required for the Claisen rearrangement reaction is higher than the activation energy required for the Cope rearrangement. In the reaction of 2-(2-methallyloxy)phenol to prepare furanol by Claisen rearrangement, it is not possible to control the reaction temperature from the perspective of thermodynamics. Upper inhibition of Cope rearrangement or reduction of its selectivity
