用氯, 溴, 二溴二烷使顺式蒎酮酸卤化得到顺-3-氯(溴)乙酰基-2,2-二甲基环丁乙酸, 用磺酰氯或N-溴代丁二酰亚胺使顺式蒎酮酸卤化可得到顺-和反-3-乙酰基-3-氯(溴)-2,2-二甲基环丁乙酸. 这里顺式异构体可分离得到. 卤化产品顺反异构体比例可从它们的甲酯的气相色谱分析简接测得.

Halogenation of cis-pinonic acid with chlorine, bromine and dioxane dibromide yielded cis-3-chloro(bromo)acetyl-2,2-dimethylcyclobutaneacetic acid, while halogenation of cis-pinonic acid with sulfonyl chloride or N-bromosuccinimide yielded cis- and trans-3-acetyl-3-chloro(bromo)-2,2-dimethylcyclobutaneacetic acid, from which cis-products could be isolated. The ratios of halogenation products were indirectly derived from GC analyses of their Me esters.
