HOMOLYTIC ADDITION OF CYCLIC ETHERS TO CROTONIC ACID
DOI:

It has been found that the route of addition of tetrahydrofuran and dioxane to crotonic acid depends on the temperature of the reaction. A feature of the synthesized oxacycloalkylbutyric acids is the existence of an intramolecular hydrogen bond involving the oxygen atom of the heterocycle.
