Cyclic structure of the β(γ)-hydroxy(mercapto)alkylimines of aldoses

Abstract

In solutions in DMSO-d₆, the products from the condensation of ethanolamine and 1,2- and 1,3-aminopropanols with aldoses are mixtures of the α- and β-pyranose forms, whereas the β-mercaptoethylimines of aldoses have the 1,3-thiazolidine structure. Glucose β-mercaptoethylimine is characterized by ring-chain tautomerism involving the α-pyranose and diastereomeric 1,3-thiazolidine tautomers.
