Synthesis and regiospecific methylation of new benzimidazolyl β-ketosulfones and β-hydroxysulfones
Condensation of 2-mercaptobenzimidazoles la-e with a-bromoacetylbenzene 2 resulting in benzimidazolyl P-ketosulfides 3a-e followed by oxidation with hydrogen peroxide giving β-ketosulfones 7a-e and subsequent reduction with sodium borohydride yielding β-h
