Cyclialkylation of arylalkyl epoxides with solid acid catalysts

Solid acids, such as zeolites and clays, catalyse the intramolecular hydrox yalkylation (cyclialkylation) of several arylalkyl epoxides in moderate to excellent conversions and selectivities. The use of solid acids in these cy clialkylations provides a cleaner, better alternative to conventional Lewis and Bronsted acids, enabling a more facile workup of reaction mixtures and , in several cases, better selectivities.
