Sulfoximines-related study has become more interesting to organic chemists over the last few decades. It includes both the steps for making NH-sulfoximine and the changes that can be made to it. NH-sulfoximines can be synthesized by a number of different successful synthetic methods. Aside from the N atom of sulfoximines, however, not many studies have done on the reactions that occurs at other locations. There are a lot of studies on N-acylation and N-arylation, but not many on N-alkylation and N-vinylation.
