Chemoselective Dieckmann cyclisation reactions on N-malonyl thiazolidine templates derived from cysteine and pivaldehyde or aromatic aldehydes may be used to access bicyclic tetramates, for which different pathways operate as a result of differing ring-chain tautomeric behaviour of the respective intermediate imines.

Chemoselective Dieckmann cyclization reactions may be used on oxazolidine and thiazolidine templates derived from various aldehydes to access bicyclic tetramates, which have potential as templates for chemical library construction. Bioassay against Staphylococcus aureus and Escherichia coli showed that these systems have little or no intrinsic antibacterial bioactivity.
