1. Crystal structure of dimethyl 2-((2Z,5Z)-5-(2-methoxy-2-oxoethylidene)-2-{(E)-[2-methyl-5-(prop-1-en-2-yl)cyclohex-2-enylidene]hydrazinylidene}-4-oxothiazolidin-3-yl)fumarate

Abstract

The crystal structure and the conformation of the title compound, C22H27N3O7S, were determined from the synthetic pathway and by X-ray analysis. This compound is a new 4-thiazolidinone derivative prepared and isolated as pure product from thiosemicarbazone carvone. The molecule is built up from an oxothiazolidine ring tetrasubstituted by a methoxy–oxoethylidene, a maleate, an oxygen and a cyclohexylidene–hydrazone. The cyclohexylidene ring is statistically disordered over two positions, resulting in an inversion of configuration for the substituted carbon.

Abstract

The title compound, C13H19N3OS, is a new thiazolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thiosemicarbazone pulegone. It crystallized with two independent molecules (A and B) in the asymmetric unit. The compound is composed of a hexhydroindazole ring system (viz. a five-membered dihydropyrazole ring fused to a cyclohexyl ring) with a thiazole-4-one ring system attached to one of the pyrazole N atoms (at position 2). The overall geometry of the two molecules differs slightly, with the mean planes of the pyrazole and thiazole rings being inclined to one another by 10.4 (1)° in molecule A and 0.9 (1)° in molecule B. In the crystal, the A and B molecules are linked via C—H...O hydrogen bonds, forming slabs parallel to the ab plane. There are C—H...π interactions present within the layers, and between the layers, so forming a three-dimensional structure.

Abstract

The absolute structure of the title compound was determined from the synthetic pathway and by resonant scattering. The compound is a new thia­zolidin-4-one derivative, prepared from (R)-thio­semicarbazone pulegone, and was isolated on crystallization from ethanol as the pure (3aS,6R)-diastereisomer., The title compound, C13H19N3OS, is a new thia­zolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thio­semicarbazone pulegone.

The compound is composed of a hexhydro­indazole ring system (viz. a five-membered di­hydro­pyrazole ring fused to a cyclo­hexyl ring) with a thia­zole-4-one ring system attached to one of the pyrazole N atoms (at position 2).
