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 ß-hydroxy aldehydes. The thiazoline residue can be removed by reduction with Al amalgam and treatment with HgCl2: J. Org. Chem., 40, 2021, 2025 (1975). Compare Thiazole, L09970, 2-Bromothiazole, A14838, and 2-(Trimethylsilyl)thiazole, B21903./n
