Reaction Steps

To a THF suspension (4.2 ml) containing triphenylmethylphosphonium bromide (0.536 g, 1.5 mmol) was added dropwise at 0° C. butyl lithium (1.4 mmol in 0.88 ml of 1.6M hexane solution). The reaction liquid was stirred at 0° C. for 30 minutes and then given 5,5-dicarboethoxy-7-octen-2-on (0.27 g, 1.0 mmol), followed by stirring at 0° C. for 1 hour. After treatment and purification as in Referential Example 9, there was obtained 0.239 g of diethyl allyl(3-methyl-3-butenyl)malonate (yields: 89%). Characteristic Values of allyl(3-methyl-3-butenyl)malonate
