The synthesis of chiral cyclobutane 1,3,4-thiadiazoline derivatives starting from (-)-α-pinene and (-)-verbenone was studied. The diastereoisomeric excesses of the products obtained depended strongly upon the starting chiral ketone. The stereochemical assignments of the synthesized compounds were performed by NMR spectroscopy, X-ray analysis, and theoretical calculations. © 2011 Elsevier Ltd. All rights reserved.
