(±)-N-[4-Acetyl-5-methyl-5-(4-methyl-cyclo-hex-3-en-yl)-4,5-dihydro-1,3,4-thia-diazol-2-yl]acetamide.

ABSTRACT: The new title thiadiazole compound, C(14)H(21)N(3)O(2)S, was semi-synthesized starting from 1-(4-methyl-cyclo-hex-3-en-yl)ethanone, a natural product isolated from Cedrus atlantica essential oil. The stereochemistry has been confirmed by single-crystal X-ray diffraction. The thia-diazo-line ring is roughly planar, although it may be regarded as having a half-chair conformation. The cyclo-hexenyl ring has a half-chair conformation. The most inter-esting feature is the formation of a pseudo-ring formed by four mol-ecules associated through N-H?O hydrogen bonds around a fourfold inversion axis, forming an R(4) (4)(28) motif.
