실험 절차
The procedure of Example 1 is repeated with 19.5 g (0.16 mol) of propylidene cyclopentanone, 0.46 g (0.02 g-atom) of sodium, 21 g (0.18 mol) of methyl acetoacetate and 100 ml of methanol. Fractional distillation yields 14 g (bp 95°-102° C. at 0.5 mm) of 5-ethylbicyclo [4.3.0] non-1-en-3-one having the structure: ##STR8##
