Abstract
Several sulfoxides with high enantiomeric purity have been synthesised using heterogeneous catalytic systems. A variety of titanium catalysts supported on Al2O3, SiO2, ZrO2 and montmorillonite, pillared clay catalysts using montmorillonite obtained from different sources and various chiral auxiliaries in presence of stoichiometric amounts of tertiary butyl hydroperoxide (TBHP) have been evaluated in asymmetric oxidation of prochiral sulfides to sulfoxides. It was found that Ti-PILC using montmorillonite K10 afforded optimum results. A probable active species responsible for high enantioselectivity is also discussed.
