  the formation of 1,2-disubstituted dihydronaphthalenes. With acyclic α,β-unsaturated carboxylic acids, the diastereoselectivity of the reaction is marginal. With secondary butyllithium, the protonolysis of the intermediate enolates gives a 1,4-addition and an average diastereoselectivity. Reaction of phenylpropiolic acid with butyllithium gives rise to the formation of a product resulting from a trans

  在 -78°C 的 THF 中，有机锂衍生物和未保护的 α,β-不饱和羧酸发生共轭加成反应。报道了 1- 和 2- 萘甲酸与各种有机锂衍生物和亲电子试剂的反应。两项 X 射线研究表明，该反应具有良好的非对映选择性：作为中间体形成的二锂化烯醇化物仅通过与有机锂相反的面添加亲电子试剂。对所得产物的 1 H NMR 谱的研究表明，这些化合物在溶液中采用优选的构象。三氟乙酸对中间体烯醇化物的质子分解以反向模式产生 1,2-二取代二氢萘的形成。对于无环 α,β-不饱和羧酸，反应的非对映选择性很小。对于仲丁基锂，中间体烯醇化物的质子分解产生 1,4-加成和平均非对映选择性。苯基丙炔酸与丁基锂反应生成三键反式加成产物；有机锂衍生物在羧基上加成α。

  α,β-Unsaturated carboxylic acids undergo predominantly conjugate addition with organolithium reagents at low temperature (–78 °C) in THF and lead to various substituted alkanoic acids after quenching with electrophiles; with (E)-3-phenylpropenoic acid, this tandem alkylation sequence also affords significant amounts of isomeric 1,3-addition products.
