A series of S-glycosyl alkyl thiols (3-10) were synthesised by 1,4 - conjugate addition of sulphur nucleophiles to glycosyl olefinic esters (1,2). The selected compounds (3,4,7,8) on oxidation with KMnO4 resulted in quantitative yield of corresponding sulphones (11-14). The synthesized compounds were screened against M. tuberculosis, though most of the compound exhibited little activity; however one of them (15) exhibited good antitubercular activity in vitro for further optimization
