Chemical Synthesis and Reactions

Abstract In recent times, synthetic organic reactions have gained significant attention as they are becoming a versatile tool in the synthesis of pharmaceuticals, agrochemicals and their intermediates. Sulfamic acid (SA) is an acid catalyst that demonstrated high efficiency in various organic transformations that will be highlighted in this review. These include efforts to develop green approaches using SA catalyst for the C−C bond formation reactions and functional group transformations, as well as the synthesis of various O− and N‐heterocyclic compounds and other miscellaneous reactions including multicomponent reactions. The easy recovery (for subsequent reuse) of the catalyst by filtration without the need for solvents is an important advantage of SA catalyst. In this review, SA promoted greener methodologies that were developed and the applicability of these methodologies are addressed.
