Crystal structure of (2S,4S)-5,5-dimethyl-2-(pyridin-2-yl)-1,3-thiazolidine-4-carboxylic acid

Abstract

In the title compound, C11H14N2O2S, the thiazolidine ring has an envelope conformation with the C atom bonded to the carboxylic acid group at the flap. Two C atoms of the thiazolidine ring adopt S conformations. In the crystal, O—H...N hydrogen bonds between the amine and carboxylic acid groups construct a helical chain structure along the a-axis direction. The chains are further connected via weak C—H...π contacts, forming a layer parallel to the ac plane.
