N-methylation of sulfoximines using methylboronic acid is reported. The reactions provide excellent yields in a short span of time under mild conditions. The optimized conditions were also found to be suitable for the N-alkylation of sulfoximine with different alkylboronic acids. In addition, N-methylation and cyclopropylation of the bioactive L-methionine sulfoximine derivative was demonstrated under standard

Starting from the development of catalytic strategies involving transition metals, more sustainable metal-free processes have been discovered. In particular, the use of hypervalent iodine reagents to mediate NH-transfer to sulfoxides is described, along with an assessment of the substrate scope. Furthermore, a one-pot strategy to convert sulfides directly into NH-sulfoximines is discussed, with N- and O-transfer

tetrafluoroborates is demonstrated in the presence of copper chloride and DABCO. A wide range of aryl and alkyl sufoximines are participated in the couplingreaction with different aryldiazonim salts bearing electron donating and withdrawinggroups and provided the desired products in 67–88% yields. The reaction proceeds through a radical mechanism.

novel approach for the synthesis of hitherto unknown α-sulfoximinophosphonate via the Kabachnik–Fieldsreaction of aldehyde, dialkylphosphite and sulfoximine in the presence of InCl3 in THF at 70 °C. α-Sulfoximinophosphonate is synthesized in good yields and its synthetic utilities are proved by functionalizing bromine through the Pd-catalyzed Suzuki–Miyaura cross-coupling reaction and reduction of a nitro
