Reaction Steps
At −78° C., lithium bis(trimethylsilyl)amide, (1.0 M in hexanes) (5 mL, 28 mmol) was added slowly to a solution of methyl 2-(trimethylsilyl)acetate (4 g, 28 mmol) in THF (30 mL). The reaction was maintained at −78° C. for 16 minutes and then 7-nitro-1-tetralone 6.1 (available from Astratech) (3 g, 16 mmol) was added in one portion, and the resulting mixture was stirred at −78° C. and allowed to warm to room temperature for 20 hours. The resulting mixture was poured into water (30 mL) and then extracted with EtOAc (300 mL). The combined organic layers were washed with brine and dried over anhydrous sodium sulfate. After removing solvent, the residue was purified by chromatography (silica gel, 1:4 EtOAc/hexane) to give 6.2 in 83% yield.
