Abstract


Although first synthesis of 1,2,4-benzotriazine was performed at the end of 19th century still new methods for their preparation are developed. This microreview combines recent (2006–2017) information on the strategies used for the synthesis of 1,2,4-benzotriazines – [4+2] cycloaddition reactions, diverse cyclocondensations, heterocyclization of N-(2-aminoaryl)hydrazides, etc.

Keywords


1,2,4-Benzotriazines; heterocyclization; N-heterocycles; aromatic compounds
