The novel 4,10-dihydro-3H-pyridazino[1,6-b]isoquinolin-10-one heterocyclic system was synthesized by acid-catalyzed recyclization of 2-(difurylmethyl)benzohydrazides as well as by recyclization of (2-carboxyaryl)difurylmethanes to isocoumarins followed by the reaction with hydrazine hydrate.
通过酸催化2-(二呋甲基)苯并酰肼的再环化以及(2-羧基芳基)的再环化合成了新型4,10-二氢-3H-哒嗪基[1,6-b]异喹啉-10-酮杂环体系二呋喃基甲烷生成异香豆素,然后与水合肼反应。
