実験手順
To a solution of N-but-3-en-1-yl-N-(4-methoxyphenyl)acrylamide (180 mg, 0.78 mmol) in degassed methylene chloride (200 mL) was added Grubbs catalyst (32 mg, 0.039 mmol) and the mixture was heated to 40° C. overnight. All volatiles were removed and the resulting material was subjected to flash chromatography (Hexanes:EtOAc 1:1) to yield 1-(4-methoxyphenyl)-5,6-dihydropyridin-2(1H)-one (158 mg, 98%).
