Regioselective monotosylation, for the first time on 2,4‐ syn & 2,4‐ anti configured ene‐tetrols and on diols & triols was achieved in excellent yields and selectivity by employing [DMAPTs] + Cl − , 1 . We also proposed and developed operational flexible preferential regio‐complimentary tosylation of cis ‐1,2‐diol moiety of pyranosides by employing 1 . Further NMR correlation for unambiguous structure determination of regioselectivity and also preferred conformations of these pyranosides were established.
