REFERENCES

• Acetaldehyde anion synthon, by metallation at the methyl group. ɑ-Mono-, di- and trisubstituted aldehydes can be prepared by successive lithiation and alkylation steps. The anion also reacts, e.g.with carbonyl groups to give precursors of ?-hydroxy aldehydes. The thiazoline residue can be removed by reduction with Al amalgam and treatment with HgCl₂: J. Org.
