The deprotonation and alkylation of 1-methylcyclohexa-2,5-diene-1-carboxylic acid has been investigated under a range of conditions. In all cases, the formation of compounds 14 was found to be completely stereoselective, although compound 14c was formed as an impurity when alkyl iodides were used as electrophiles, and doubly-alkylated compounds 17 were formed in some cases when alkyl bromides were used.
在一系列条件下研究了 1-甲基环己-2,5-二烯-1-羧酸的去质子化和烷基化。在所有情况下,发现化合物14的形成是完全立体选择性的,尽管当使用烷基碘作为亲电试剂时形成作为杂质的化合物14c,并且当使用烷基溴时在某些情况下形成双烷基化的化合物17。
