Synthesis of sulfonamide and their synthetic and therapeutic applications: Recent advances

A sulfonamide is a functional group that is the basis of several sulfa drugs and thereby are very much important scaffolds in medicinal as well as in synthetic organic chemistry. Recently very important methodologies have been developed for the synthesis of sulfonamide. This complex review article covers the recent developments (mainly in the period 2013–2019) of powerful methodologies for the synthesis of sulfonamide compounds, particularly where SO2N(R) moiety is not present in a cyclic structure and their applications in various fields during this period. A critical view of the mechanisms of the developed methodologies together with the scope and limitation of these methods adds an extra dimension to the text.
