実験手順

N-benzyl-N-methoxymethyl-N-(trimethylsilylmethyl)amine (5.0 g, 21.06 mmol) was added dropwise with a syringe over 30 minutes to a suspension of (E)-2-(2-bromostyryl)-4-chlorophenyl acetate (Example 1; 7.0 g, 19.9 mmol) in toluene (25 ml) containing trifluoroacetic acid (3 drops) while stirring at room temperature. After additional stirring for one hour water (10 ml) was added. The toluene layer was separated. The aqueous layer was extracted with toluene (25 ml). The combined organic layers were dried with Na2SO4 and evaporated under vacuum to give the crude cycloadduct as a clear and colorless oil, 10.76 g (>100%) in quantitative yield.
