2-ones (IV) were prepared by the reaction of 2-chlorotropone with ethyl phenylacetate and with ethyl benzoylacetate respectively. The reactions of III with malononitrile or ethyl cyanoacetate gave 1-phenylazulene derivatives, from which I was derived. On the other hand, the reactions of IV with ethyl cyanoacetate or diethyl malonate gave 2-phenylazulene derivatives, from which II was derived.
1-苯基天青素 (I) 和 2-苯基天青素 (II) 由类肌醇化合物合成。3-苯基-(III)和3-苯甲酰基-2H-环庚[b]呋喃-2-酮(IV)分别通过2-氯托酮与苯乙酸乙酯和苯甲酰乙酸乙酯反应制备。III 与丙二腈或氰基乙酸乙酯反应生成 1-苯基芴衍生物,I 由其衍生。另一方面,IV与氰基乙酸乙酯或丙二酸二乙酯的反应得到2-苯基芴衍生物,从中衍生出II。
