Wide-pored β-zeolite or natural clay askanite-bentonite, when used as catalysts to perform reactions of terpene olefin derivatives with aldehydes, provide unusual transformations yielding new polyheterocyclic compounds.

It was established that 2-carene-4α- and 3-carene-2α-alkylmethanols and hydroxy-p-menthadienes undergo heterocyclization in superacidic media (HSO3F-SO2FCl, -100 deg C) with the formation of bicyclic ethers containing oxabicyclooctane, oxabicyclooctane, andoxabicyclononane skeletons, depending on the structural characteristics of the initial substances.
