This review considers methods for the synthesis of pyrimido[1,2-a]indoles and their ring-fused derivatives, covering publications from the last 10 years. Depending on the synthons used for assembling the target structure, three main approaches to the synthesis of pyrimido-[1,2-a]indoles can be distinguished: annulation of a pyrimidine ring to 2-aminoindoles, modification of other indole derivatives, and miscellaneous methods.

嘧啶并[1,2-a]吲哚的合成（小评）

本综述考虑了嘧啶并 [1,2- a ] 吲哚及其稠环衍生物的合成方法，涵盖了过去 10 年的出版物。根据用于组装目标结构的合成子，可以区分三种主要的嘧啶基-[1,2- a ]吲哚合成方法：嘧啶环环化为 2-氨基吲哚、其他吲哚衍生物的修饰和杂项方法。
