Two new syntheses have been developed for the preparation of substituted pyrido[2,3,4-kl]acridines. The first synthesis involves a Skraup reaction and a nitrene insertion whereas the second includes a new pyridine ring synthesis starting from a 1-amino group on acridine and taking advantage of the active 9-position of the latter heterocycle.

吡啶并[2,3,4-kl] ac啶。第一种合成涉及Skraup反应和氮烯插入,而第二种合成包括新的
吡啶环合成,该合成是从ring啶上的1-
氨基开始并利用后者杂环的活性9位进行的。
