実験手順

As described in General Procedure F-1, 1-(4,4-dimethyl-6-ethoxy-1-isopropyl-3,4-dihydronaphthalen-7-yl)ethanone (Compound A-24, 240 mg, 0.840 mmol) and triethyl 2-fluoro-2-phosphonoacetate (0.51 mL, 2.52 mmol) were reacted with lithium diisopropylamide (2.60 mmol) in THF (2 mL) to produce the title compound after purification by flash column chromatography (silica gel, 97:3 hexane/ethyl acetate).
