실험 절차

A solution of 7.7 g of ethyl diethyl-phosphono-fluoroacetate (prepared by process of Ann. Chem., 1964, p. 6741), 60 ml of 1,2-dimethoxyethane and 4 g of (1R, trans) 2,2-dimethyl-3-formyl-cyclopropane-carboxylic acid was added over 30 minutes at 2° to 10° C. to a suspension of 2.6 g of a 60% sodium hydride in oil suspension and 60 ml of 1,2-dimethoxyethane and the mixture was stirred at 5° C. for 15 minutes, and then at room temperature for 3 hours. The resulting solution was poured into aqueous monosodium phosphate solution at 5° C. and the mixture was stirred for 10 minutes. The mixture was extracted with ethyl acetate and the organic phase was washed with water, dried and evaporated to dryness at 40° C. under reduced pressure to obtain 6.5 g of an oil residue. The latter was chromatographed over silica gel and was eluted with a 70-30-1 hexane-ethyl acetate-acetic acid mixture to obtain 4 g of (1R,trans) 2,2-dimethyl-3(E)-[2-fluoro-3-oxo-3-ethoxypropenyl]-cyclopropane-1-carboxylic acid
