The title compound, C18H20N4O2S2, is a new 1,3,4-oxadiazole and a key pharmacophore of several biologically active agents. It is composed of a methyl(thiophen-2-yl)-1,3,4-oxadiazole-2(3H)-thione moiety linked to a 2-methoxyphenyl unit via a piperazine ring that has a chair conformation. The thiophene ring mean plane lies almost in the plane of the oxadiazole ring, with a dihedral angle of 4.35 (9)°. The 2-methoxyphenyl ring is almost normal to the oxadiazole ring, with a dihedral angle of 84.17 (10)°. In the crystal, molecules are linked by weak C-H
S hydrogen bonds and C-H![[pi]](http://scripts.iucr.org/logos/entities/pi_rmgif.gif)
interactions, forming layers parallel to the bc plane. The layers are linked via weak C-HO hydrogen bonds and slipped parallel - interactions [intercentroid distance = 3.6729 (10) Å], forming a three-dimensional structure. The thiophene ring has an approximate 180° rotational disorder about the bridging C-C bond.
The pseudoglycosyltransferase (PsGT) VldE is a glycosyltransferase-like protein that is similar to trehalose 6-phosphate synthase (OtsA). However, in contrast to OtsA, which catalyzes condensation…
