Sulfoximine‐Directed Arene ortho‐Lithiation
European Journal of Organic Chemistry, Volume 2021, Issue 46, Page 6229-6246, December 14, 2021., 2021 The growing importance of sulfoximines in medicinal chemistry has led to a renewed interest in their synthesis and functionalization. This review describes the directed ortho‐lithiation of S‐aryl sulfoximines. Discussed are the synthesis and reactivity of five different types of o‐lithiosulfoximines, including o‐lithiosulfoximines with and without α ...

Synthesis and Transformations of NH‐Sulfoximines
Chemistry – A European Journal, Volume 27, Issue 69, Page 17293-17321, December 9, 2021., 2021 This review considered recent progress and achievements in the synthesis and transformation of NH‐sulfoximines. The development of strategies for direct and selective preparation of NH‐sulfoximines, even in enantioenriched form or by using sustainable approaches and continuous flow synthesis, are reported. Transformations of sulfoximines by N−S, N−P, N−
