A novel rearrangement has been found between oxazolidinethiones and acyl halides under N-acylation reaction conditions to afford N-substituted 2,4-thiazolidinediones and N-substituted 1,3-thiazinane-2,4-diones. These heterocycles were used for the synthesis of chiral allylic ureas and α-methyl-β-amino acids.
(S)-4-Isopropyl-5,5-dimethyl-1,3-oxazolidinethione as chiral auxiliary for the intramolecular sulfur transfer in α,β-unsaturated N-acylimides, promoted by NbCl5

The 1,3-oxazolidinethione 4 has been synthesized from (S)-valine and used in the intramolecular sulfur transfer in its N-enoyl derivatives in the presence of NbCl5 as catalyst, which, moreover, works as an indicator of the course of the reactio
