A series of novel peri-fused azines, pyrimido[4,5,6-de]quinolino[2,3-b][1,8]naphthyridines and benzo[b]pyrimido[4,5,6-de][1,8]naphthyridines, were prepared via the base-promoted double tandem cyclization of 4-(1-acyl-2,2-diaminovinyl)-6-(haloaryl)pyrimidine-5-carbonitriles. This transformation represents a rare example of the one-pot synthesis of peri-annulated polycyclic structures from non-fused
一系列新型的周边融合杂志,嘧啶基[4,5,6- de ]喹啉[2,3- b ] [1,8]萘啶和苯并[ b ]嘧啶[4,5,6- de ] [1通过碱促进的4-(1-酰基-2,2-二氨基乙烯基)-6-(卤代芳基)嘧啶-5-腈的双串联环化反应制备1,8]萘啶。这种转化代表了由非稠合杂环一锅合成周环多环结构的罕见例子。发现合成的嘧啶并[4,5,6- de ]喹啉基[2,3- b ] [1,8]萘啶是发光体。
