Photocatalyzed sulfoximination/amidation of (Het)arylethenes tethered N-tosyl amide: a versatile entry to sulfoximidoyl β- and γ-lactams†

Lactam and sulfoximine motifs are common in natural and biologically active molecules, and alkenes are important building blocks in synthetic chemistry. Through photoredox-mediated formation of cation intermediates, we have developed a highly versatile method for preparing various sulfoximidoyl lactams via C–N bond formation between CC and amide motifs. Mild reaction conditions, broad functional group tolerance and excellent trans-selectivity of this method would make it a general and efficient approach towards novel compounds containing valuable sulfoximine and lactam motifs for possible therapeutic use.
