The enanti-omerically pure title compound, C(11)H(15)NO(4)S, contains a pyramidal N atom with an S-N bond length of 1.6262 (8) Å. In the crystal, mol-ecules are linked to form chains parallel to the a axis by the hydrogen bond from NH to the carbonyl oxygen. C-H⋯O inter-actions are also present.
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. Alkylation of 4a-e with 1.0 mole eq. of substituted benzyl… (More)
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).
