The total synthesis of ent-penilactone A and penilactone B has been achieved via biomimetic Michael reactions between tetronic acids and o-quinone methides. A five-component cascade reaction between a tetronic acid, formaldehyde, and a resorcinol derivative that generates four carbon–carbon bonds, one carbon–oxygen bond, and two stereocenters in a one-pot synthesis of penilactone A is also reported
对苯二甲内酯A和半乳糖内酯B的全合成已经通过tetronic酸和邻醌甲基化物之间的仿生迈克尔反应得以实现。还报道了在一锅法合成戊内酯A中,四酸,甲醛和间苯二酚衍生物之间的五组分级联反应,该反应生成四个碳-碳键,一个碳-氧键和两个立体中心。
