Synthesis
_synthesis.svg)
The aldol condensation between two equivalents of acetone gives mesityl oxide (1), with isophorone as a side-product of this reaction. Ammonolysis of mesityl oxide formed diacetonamine (2). The reaction of this product with acetone then gives triacetonamine (3). N-Methylation of the secondary amine gives 1,2,2,6,6-pentamethylpiperidin-4-one (4). Cyanohydrin formation gives (5). Esterification of the tertiary alcohol with benzoyl chloride gives (6). Pinner reaction of the nitrile with acidified ethanol affords alpha-eucaine (7).
