title: Exploring the reactivity of N-alkynylated sulfoximines: [2 + 2]-cycloadditions.
abstract: To assess the potential of N-alkynylated sulfoximines as new (chiral) reagents for organic synthesis, their reactivity profile in numerous synthetic processes is under investigation. When reacted with ketenes, the alkynylated-sulfoximines undergo a [2 + 2]-cycloaddition process to afford sulfoximine-functionalized cyclobutenones in excellent yields.
