The most recent approaches toward isoxazolo[4,5-b]pyridine derivatives are discussed. The microreview covers the latest selected examples (2012–2022) on the synthesis of isoxazolo[4,5-b]pyridines via two main approaches: annulation of a pyridine ring to 4-aminoisoxazoles and isoxazole ring closure in functionalized pyridine derivatives. In addition, some special cases of the isoxazolo[4,5-b]pyridine system formation will be mentioned.
