国外对蒎酮酸的制备、反应及其衍生物的应用报道颇多。为了开发利用我国丰富的松节油资源,我们对顺式蒎酮酸(1)的卤代反应进行了研究。关于蒎酮酸的溴代反应已有研究,而氯代反应还未见报道。我们选用了氯气和氯化硫酰作为氯代反应试剂。在酸性条件下1与氯反应时,得到顺式-2,2-二甲基-3-氯乙酰基环 Foreign countries on the preparation of pinane acid, reaction and its derivatives have been reported many applications. In order to develop and utilize our rich turpentine resources, we have studied the halogenation reaction of cis-pinane acid (1). Bromination reaction of benzenesonic acid has been studied, and the chlorination reaction has not been reported yet. We use chlorine and thionyl chloride as chlorination reagents. When reacted with chlorine under acidic conditions 1, a cis-2,2-dimethyl-3-chloroacetyl ring is obtained
