Аннотация:The review is devoted to the use of [1,2,3]triazolo[1,5-a]pyridines as precursors of tautomeric 2-(diazomethyl)pyridines. This methodology represents a convenient tool for the synthesis of various types of nitrogen-containing heterocycles. Both noncatalytic transformations and cascade reactions involving metal carbenes, which have been intensively studied in recent years, are considered. Major approaches to the preparation of [1,2,3]triazolo[1,5-a]pyridines are also summarized in the review.
