optimized reaction conditions are well suited to the task of N-vinylation of sulfoximine with trans-2-phenylvinylboronic acid. N-Arylation of sulfoximines with different arylboronic acids, including sterically hindered boronic acids, is achieved using copper(I) iodide and 4-DMAP at room temperature. Moreover, N-arylation of biologically relevant l-methionine sulfoximine is demonstrated for the first time

Herein, we disclose a metal-free novel approach for the synthesis of N-(α-substituted)alkyl sulfoximines/sulfonimidamides via one-pot multicomponent Petasis reactions of aryl boronic acids, ortho-hydroxyarylaldehydes and sulfoximines/sulfonimidamides in moderate to very good yields. The presence of two chiral centres provides a mixture of diastereomers almost in a 1 : 1 ratio, which are separated successfully

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
