実験手順
A flask was charged with CH2Cl2 (25 mL), 2,5-dimethyl-2,4-hexadiene (25 mL) and 0.45 g of the Cu,K-PFIEP[SO3H] catalyst, prepared as described above. A solution of ethyl diazoacetate (2.5 g) in CH2Cl2 (25 mL) was added slowly dropwise and the resulting reaction mixture was stirred for 24 hours at ambient temperature. Gas chromatography analysis showed that the resulting product contained cis- and trans-ethyl chrysanthemumates in a 1:1.66 isomer ratio and a combined yield of 89.6%.
