YieldReaction ConditionsOperation in experiment
With triethylamine; In dichloromethane; at 20℃; for 2h; General procedure: A solution of keto esters 4a-d (1 mmol) and triethyl orthoformate (2.50 mL, 1.5 mmol) in acetic anhydride (5.5 mL, 6 mmol) was stirred for 8 h at reflux and concentrated under reduced pressure to give crude products 5a-d as yellow oils. To a solution of 5a-d and triethylamine (2.80 mL, 2 mmol) dissolved in dichloromethane (10 mL) was added (1R,2S)-fluorocyclopropanaminetosylate (3.71 g, 1.5 mmol) in portions and stirred for 2 h at room temperature, and then concentrated under reduced pressure togive crude products 6a-d as yellow oils. A mixture of 6a-d, DMF (10 mL) and K2CO3 (2.80 g, 2 mmol) was stirred for 1 h at 90 oC and then poured into water (100 mL). The precipitate was collected by filtration and purified by silica gel column chromatography to give the title compounds 7a-d (42.5-61.3percent, from 4a-d) as white solids.
