Solvent Effects in Biomass Processing: α- and β-Pinene Oxide Rearrangements.

Popis výsledku v původním jazyce

α- and β-Pinenes are compounds naturally occurring in pine resins (or in other conifers) and are the main constituents of turpentine oil. Many important compounds may be derived from pinenes, most of them find their usage in perfume chemistry. Through the oxidation of pinenes, pinene oxides may be prepared. Depending on the reaction conditions, different important products are obtained from the rearrangement of α- or β-pinene oxides. α-Pinene oxide serves as a starting material for the production of campholenic aldehyde (a fragrant compound) or trans-carveol (fragrant and chemotherapeutical properties). Dependently on acid sites present on the catalyst surface, the selectivity may be directed. The chosen solvent may also play the same role in directing the selectivity. Strong basic polar solvents induce the selectivity towards trans-carveol whereas low-basic solvents towards campholenic aldehyde. Similarly, from β-pinene oxide, two types of important compounds may be obtained: myrtenol or myrtanal (serving as fragrances, produced using low basic non-polar solvents) and perillyl alcohol (a compound with interesting biological activity, produced using strong basic solvents). The use of a large of variety of solvents is discussed in this chapter, varying from non-polar low basic solvents (e.g., toluene) to polar strong basic solvents (e.g., DMSO) showing that the properties of different solvents strongly influence the product composition of both studied reactions.
