New Reactions of Isoprenoid Olefins with Aldehydes Promoted by Al2O3-SiO2 Catalysts.

Abstract 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.
