(E)-hex-3-en-2-one

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of t-BuOK (17.2 g, 153 mmol) and cyanoacetamide (13 g, 153 mmol) in CH3CN (225 mL) was added (3E)-3-hexen-2-one (15 g, 153 mmol) at room temperature under N2 atmosphere. The reaction mixture was stirred for 30 min. To the reaction mixture was added additional t-BuOK (51.4 g), and the N2 was displaced by oxygen. After stirring for 1 h without external cooling, the mixture was diluted with 4 N HCl, which was added slowly and with good stirring. The mixture was filtered, washed with EtOH, dried to give 6-ethyl-4-methyl-2-oxo-1,2-dihydro-3-pyridinecarbonitrile (5 g, 21%). 1H NMR (400 MHz, DMSO-d6) δ 12.33 (br. s., 1H), 6.18 (s, 1H), 2.45 (q, 2H), 2.30 (s, 3H), 1.11 (t, 3H). After stirring for 1 h without external cooling was added slowly and with good stirring The mixture was filtered washed with EtOH dried
