An efficient oxidative chlorination of thiols to Nα-protected amino alkyl sulfonyl azides is delineated. The reaction involves in situ generation of sulfonyl chloride employing Nchlorosuccinimide and tetrabutylammonium chloride-water in acetonitrile, followed by the reaction with sodium azide. The protocol is simple, straight forward, mild and high yielding. Amino acids with simple as well as bifunctional

An efficient one-pot synthesis of Nα-protected S-linked 1,3,5-triazine tethered peptidomimetics is described. The protocol involves a three-component condensation reaction employing Nα-protected amino alkyl isothiouronium salt, formaldehyde and aminoacidester or aryl amine as reactants. Various aryl amines with substitutions and aminoacids with simple as well as bifunctional side chains were employed
