    Notes: By acetalisation of L-menthone (2) with mercaptoacetic acid and derivatives of benzylamine, the spirocyclic N,S-acetals 3 were obtained as single diastereomers. The reaction of an epimeric mixture of unsubstituted thiazolidinones 4 with acetic anhydride or allyl iodide afforded homochiral N-acetyl (5) or N-allyl N,S-acetals (6), respectively. The configuration of the new stereogenic centres were proven by X-ray crystallography.
