Reaktionsschritte
To a mixture solution of 0.42 g of (1R)-trans-2,2-dimethyl-3-((Z)-1-propenyl)cyclopropanecarboxylic acid, 0.49 g of (2,3,5,6-tetrafluorophenyl)methanol, 0.93 g of triphenylphosphine and 20 ml of tetrahydrofuran, 2.0 ml of 40% toluene solution containing diisopropyl azodicarboxylate was added. After one day, the reaction solution was concentrated under reduced pressure and the residue was subjected to silica gel column chromatography (eluent: hexane/ethyl acetate=20/1) to give 0.80 g of (2,3,5,6-tetrafluorophenyl)methyl (1R)-trans-2,2-dimethyl-3-((Z)-1-propenyl)cyclopropanecarboxylate
