Abstract


The review presents the main methods for the synthesis of pyrido[1,2-a]indoles and their annulated and conjugated derivatives over the past 10 years. The approaches are divided into three groups depending on the
starting compounds: construction of the pyridine nucleus on the indole fragment, cyclization using benzylsubstituted pyridines, and formally one-step process via aryne intermediates.
