    • 2O]-Ala-Fmoc 5b, 5c were studied. The alanyl methyl groups were resonated as distinct doublets at δ 1.30 and 1.34 for 4b and at δ 1.28 and 1.32 for 4c, at δ 1.31 and 1.35 for 5b and at δ 1.28 and 1.32 for 5c supporting their enantiopurity.

    • The enantiopurity of each of the above compounds was further supported by the HPLC analysis by using column: Agilent Eclipse XDB-C18 (flow rate 0.5 mL/min; eluting with 0.1% TFA water-acetonitrile; 30-100% in 30 min). Diacylhydrazines 3b and 3c showed single peak with retention time at 12.48 and 12.06 min, respectively. Similarly in the case of 1,3,4-thiadiazole derivatives, single retention time at 9.55 min for 4b and at 9.43 min for 4c were observed, whereas the corresponding enantiopure 1,3,4-oxadiazoles 5b and 5c showed single retention times at 11.73, 11.67 min, respectively.
