反応手順
4.3 g (0.03 mol) of pentane-2,3,4-trione 3-(O-methyloxime) and 6.2 g (0.06 mol) of trimethyl orthoformate were dissolved in 15 ml of methanol and admixed with a spatula tip of p-toluenesulfonic acid. The mixture was subsequently stirred at 50° C. for 5 h, after which the solvent was distilled off. This gave 5.5 g of an oil (98% yield) (phys. data see Tab. 1).
