The most recent advances in the synthesis of heterocyclic compounds via insertion of sulfur dioxide reported from 2015 to 2018 are summarized. Methods described here are organized in several sections depending on the source of SO2: sodium or potassium metabisulfite (M2S2O5), SO2 adducts with nitrogen-containing heterocycles DABSO and DMAP·SO2, ex situ formed SO2, and intramolecularly released SO2.

Keywords: insertion heterocyclic; insertion; modern approaches; so2 insertion; heterocyclic synthesis; approaches so2
