Halogenation of pinonic acid

Abstract

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.
