実験手順
To a solution of N-allyl-N-(4-methoxyphenyl)acrylamide (150 mg, 0.69 mmol) in degassed methylene chloride (400 mL) was added Grubbs catalyst (58 mg, 0.069 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)-1,5-dihydro-2H-pyrrol-2-one (110 mg, 86%).
