Two diastereomers of d-limonene-derived five-membered cyclic carbonates were prepared from the corresponding isomers of d-limonene oxide with CO2. Their syntheses were catalyzed by commercially available tetrabutylammonium chloride with high stereoselectivity. The reaction behavior dependent on the reaction conditions such as CO2 pressure was clarified.
