                                    A number of new chiral Schiff bases were synthesized starting from accessible monoterpene (+)-3-carene, and the products were used as ligands in metal complex-catalyzed oxidation of sulfides to chiral sulfoxides. The optical purity and the sign of optical rotation of chiral sulfoxides were found to strongly depend on the oxidation temperature.
