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.

Homochiral 1,3-oxazolidine-2-thiones and 1,3-thiazolidine-2-thiones are useful chiral auxiliaries in asymmetric synthesis. Our interest in chiral amino dienes drove us to consider the preparation of dienes (1a) and (1b) bearing those auxiliaries. Trying t
