A convenient and simple method for the synthesis of 1-methoxy-5,10-dioxo-5,10-dihydro-1H-benzo[g]isochromene-3-carboxylic acid (3-(dimethylamino)propyl)amide 4c was developed. The key step involves the easy formation of 1,3-disubstituted cyclic alkenyl ether, an important framework of isochromene natural products, with a dual role Pd(II) catalyst.
开发了一种简便的合成1-甲氧基-5,10-二氧代-5,10-二氢-1H-苯并[g]异亚甲基-3-羧酸(3-(二甲基氨基)丙基)酰胺4c的方法。关键步骤涉及容易形成的1,3-二取代的环状烯基醚,这是异色烯天然产物的重要框架,具有双重作用的Pd(II)催化剂。
