在氯化鋁的催化影響下以丁二酸酐作用於環已烯而製得γ-(Δ～1-環已烯基)-γ-丁酮酸。其他的Lewis酸如氯化鐵及氯化錫都經用作催化劑而進行試驗;但未得滿意的結果。將γ-(Δ～1-環己烯基)-γ-丁酮酸還原為γ-(Δ～1-環己烯基)丁酸時,Wolff-Kishner及黄鳴龍的方法都經過了試驗,但僅前法獲得成功。最後將广γ-(Δ～1-環己烯基)-丁酸環化而成△9:10-α-八氫萘酮則是以通常的Darzens法完成的。

γ-(△1-Cyclohexenyl)-y-ketobutyric cinic anhydride on cyclohexene with acid was prepared in an experiment by action of sucaluminium chloride as catalyst. Meanwhile other catalysts of the Lewis acid type, such as ferric chloride and stannic chloride, were also tried, but the results were not satisfactory. In reducing γ-hyclohexenyl)-γ-ketdbutyric acid to γ-(△1-cyclohexenyl).butyric acid, both Wolff-Kishner's method and Huang Minlon's modification were experimentally employed, the result being unexpectedly in favor of the former.
