A NEW METHOD FOR THE SYNTHESIS OF BICYCLIC ETHERS FROM TERPENOID ALCOHOLS OF THE CARANE AND MENTHANE SERIES
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.
