In this review, we consider 1, 3-dipolar cycloaddition reactions between azomethine ylides
and alkynes, resulting in the formation of pyrroles, as well as their hydrogenated and fused …

This review article describes methods for the preparation of pyrrolo [1, 2-a] quinoxalines,
covering literature sources from the last 10 years. The attention was largely paid to new …

A facile and environmentally benign Pictet–Spengler strategy for the synthesis of a series of
