Chiral recognition ability of amylose derivatives bearing regioselectively different carbamate pendants at 2,3- and 6-positions

•Synthesis and chiral recognition of novel amylose derivatives.•Novel amylose derivatives with regioselective substituent at 2,3- and 6-positions.•Regioselective protection at 2,3-positions using bulky trimethylphenyl group.•Racemic compounds better resolved on the obtained CSPs than Chiralpak AD.•Chiral recognition delicately depends on the substituents.
