(4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-dicarbonitrile
The title compound, C7H8N2O2, formed by dehydration of the corresponding dicarboxamide, crystallizes as rectangular prisms. The mol-ecules have a C 2 axis of symmetry through the C atom bearing the methyl groups and the mid-point of the ring C-C bond, and the 1,3-dioxolane ring adopts the extreme twist conformation of the two possible with this symmetry. This brings the two nitrile groups neare...

In the title compound, C(17)H(20)N(2)O(2)S(2), the five-membered heterocycle exhibits an envelope conformation and the mol-ecular chirality and configuration are well preserved from l-tartaric acid. The dihedral angle between the two thio-phene rings is 17.0 (2)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯S hydrogen inter-actions, which are effective in the stabilization of the cry...
متن کاملThe microbial metabolism of thiophen-2-carboxylate.
1. An organism was isolated by enrichment culture that was capable of using thiophen-2-carboxylate as sole source of carbon, energy and sulphur for growth. 2. Analysis of the cellular protein after growth of the organism on thiophen-2-[(14)C]carboxylate showed that only glutamate, proline and arginine were labelled. All the radioactivity in the glutamate was confined to C-1. 3. In the presence ...

متن کاملSpiro[1,3-dioxolane-2,3′-indolin]-2′-one
The title compound, C(10)H(9)NO(3), was synthesized by the condensation reaction of isatin (systematic name 1H-indole-2,3-dione) with glycol in presence of p-toluene-sulfonic acid. The indol-2-one ring system is essentially planar [N-C-C-C torsion angle = 3.1 (2)°], and the 1,3-dioxolane ring is slightly distorted. The crystal structure exhibits inter-molecular N-H⋯O hydrogen bonds.
