Abstract:
The present invention relates to a process for enantioselective synthesis of substituted pyridinylmethyl sulfinyl-benzimidazole of compound of Formula (I). The process includes enantioselective catalytic oxidation of a substituted pyridinylmethyl prochiral sulfide derivative of compound of Formula (II) with an oxidizing agent in the presence of a chiral transition metal complex and a base in the absence of an organic solvent.
