cycloadditions that yield stable 1:1 cycloadducts is discussed on the basis of steric interactions into the pyrimido[4,5-c]isoquinoline-7,10-quinones. The access to angucyclinone AB-pyridopyrimidine analogues from Diels–Alder adducts and preliminar evidences on their antitumour activities are also reported.
由酰基氢醌和1,3-二甲基-5-氨基尿嘧啶制备两个嘧啶并[4,5 - c ]异喹啉-7,10-醌及其与1-三甲基甲硅烷基氧丁二烯和1-二甲基氨基-3-甲基-1-氮杂丁二烯的环加成反应描述。基于与嘧啶并[4,5 - c ]异喹啉-7,10-醌的空间相互作用,讨论了产生稳定的1:1环加合物的这些环加成物的卓越区域控制。还报道了从Diels-Alder加合物获得angucyclinone AB-吡啶并嘧啶类似物的方法,以及有关其抗肿瘤活性的初步证据。

search for newpotentially anticancer drugs, series of angucyclinone aza-analogues containing pyridine and pyridopyridazine rings have been designed and synthesized by a highly efficient sequence involving a one-pot step for the synthesis of tricyclic quinone intermediate and highly regiocontrolled cycloaddition reactions with polarized 1,3-dienes. The new N-heterocyclic angular quinones were evaluated
