2-(1-[(4-Chloro/methylphenylsulfonylamino)alkyl]-5-thioxo-4,5-dihydro-1,3,4-oxadiazoles (4a-e) were synthesized, in four steps, via the sulfonyl derivatives of l-amino acids (l-alanine, l-methionine and l-phenylalanine) 1a-e, the esters 2a-e, the hydrazides 3a-e and finally the cyclization to 4a-e.

The enanti-omerically pure title compound, C(12)H(16)ClNO(4)S(2), contains a pyramidal N atom with an S-N bond length of 1.6306 (15) Å. Mol-ecules are linked to form chains parallel to the a axis by classical N-H⋯O hydrogen bonding involving a sulfonyl O atom, supported by three weak C-H⋯X inter-actions. (X = S, O).
