The palladium-catalyzed one-pot sequential reaction of propiolic acid derivatives with lithium halides first, and then with terminal alkynes or alkenes affords conjugated (2Z) -en-4-ynoic and (2Z,4Z)- and (2Z,4E)- dienoic acid derivatives with high stereoselectivity.
钯催化的丙酸衍生物与卤化锂的一锅顺序反应,然后与末端炔烃或烯烃进行单锅顺序反应,得到共轭的(2Z)-en-4-炔酸和(2Z,4Z)-和(2Z,4E)-具有高立体选择性的二烯酸衍生物。
