developed, based on the reaction of 2-naphthyl ethers with an equimolar quantity of 1,3,5-triazines in polyphosphoric acid. With a 2.5 molar excess of 1,3,5-triazines in polyphosphoric acid, the products of 1,6-diacylation (diformylation) are formed. Isoquino[6′,5′,4′:10,5,6]anthra[2,1,9-def]isoquinoline is formed upon reaction of a 1.5 molar excess of 1,3,5-triazine with naphthalene in polyphosphoric acid
为4的合成的新方法ħ -苯并[ DE ]异喹啉-4-酮已被开发,基于2-萘基醚与1,3,5-三嗪在多磷酸等摩尔量的反应。在多磷酸中以2.5摩尔过量的1,3,5-三嗪,形成1,6-二酰化(二甲酰化)产物。异喹啉[6',5',4':10,5,6]蒽[2,1,9- def ]异喹啉是在多磷酸中使1.5摩尔过量的1,3,5-三嗪与萘反应生成的在130-140˚C下。 1,3,5-三嗪-多磷酸-萘-酰化-4 H-苯并[ de ] isoquinolin-4-ones-isoquino [6',5',4':10,5,6]蒽[2,1 ,9- def ]异喹啉
