The conversion of caryophyllene upon contact with Al2O3 and SiO2 impregnated with sulfuric acid was carried out, and the components of the resulting mixtures were identified. Having in hands such “standard” mixtures greatly facilitates identification of components of sesquiterpene fractions of essential oils and other mixtures of natural origin. The catalytic activity of silica gel impregnated with

A gram‐scale synthesis of psiguadial B, a purported inhibitor of human hepatoma cell growth, has been achieved in onestep by a biomimetic three‐component coupling of caryophyllene, benzaldehyde, and diformylphloroglucinol. This cascade reaction is catalyzed by N,N′‐dimethylethylenediamine, and proceeds at ambient temperature to generate four stereocenters, two rings, one C−O bond, and three C−C bonds
