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

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.
