実験手順

A solution of 1,1,1-trimethoxy-5-hexyne (3.90 g, 0.023 mole) in dry tetrahydrofuran (50 mL) was stirred at -78° and treated with n-butyllithium (1.6M in hexane; 15 mL, 0.024 mole). The solution was stirred for 30 minutes, then treated with a solution of 1-benzyloxy-2-naphthaldehyde (4.25 g, 0.016 mole) in dry tetrahydrofuran (12 mL). The reaction mixture was allowed to warm to room temperature, stirred for 4 hours, and poured into water. The crude product was isolated by extraction with ether and chromatographed with 3:1 ether/hexane. This afforded the title compound (6.15 g, 97%) as an oil.
