, p. 1051 - 1058 (2018/10/02)
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 greatl

H3PW12O40 (PW), the strongest heteropoly acid in the Keggin series, is an active and environmentally friendly catalyst for the liquid-phase conversion of β-caryophyllene (1) to β-caryolanyl acetate (2) in homogeneous and heterogeneous systems. An efficient and clean method for the synthesis of 2, providing a mixture containing two stereoisomeric β-caryolanyl acetates 2a and 2b, 2a/2b = 80/20 mol/mol, with 100% GC yield, has been developed using PW as a homogeneous catalyst under mild reaction conditions. The reaction occurs at 25 °C with a catalyst turnover number of 2000. The catalyst can be recovered without neutralization and reused without loss of activity and selectivity.

The conformational composition of caryophyllene was analyzed by the computational methods of molecular mechanics and also the 13C NMR spectra.The conformationally controlled reactions of caryophyllene in superacids lead to mixtures of tricyclic compounds with new types of skeletons, which can be produced as the sum of the products from the "quenching" of the ions formed from clovene and 1-substituted caryolanes under the same conditions.
