α-Azido carbonyl compounds bearing a 2-alkenylaryl moiety in the α-position are found to be promising precursors in the synthesis of isoindoles via 1,3-dipolar cycloaddition of azides to alkenes. Applications of these isoindoles in the preparation of 1,2,3,4-tetrasubstituted naphthalene and 9,10-disubstituted anthracene derivatives were developed via [4+2]-cycloaddition reactions of isoindoles with
发现在α-位置带有2-链烯基芳基部分的α-叠氮羰基化合物是通过叠氮化物与烯烃的1,3-偶极环加成合成异吲哚的有希望的前体。这些异吲哚在制备1,2,3,4-四取代的萘和9,10-二取代的蒽衍生物中的应用分别是通过异吲哚与乙酰二羧酸二甲酯和苯并炔的[4 + 2]-环加成反应,然后进行脱氨基反应而开发的芳香化。 异吲哚-有机叠氮化物-1,3-偶极环加成-芳烃-苯并
