Metal-Free Approach for the Synthesis of N-Aryl Sulfoximines via Aryne Intermediate
摘要:
A metal-free and operationally simple N-arylation of NH-sulfoximines with precursors is reported. Transition metal-free reaction conditions and Shorter reaction times are the highlights of the present method. The mild optimized condition was :also found to be suitable with enantiopure substrates.

This is the first report on the synthesis and characterization of N-iodo sulfoximines. The synthesis was designed as a room temperature one-pot cascade reaction from readily available sulfides as starting compounds, converted into sulfoximines by reaction with ammonium carbonate and (diacetoxyiodo)benzene, followed by iodination with N-iodosuccinimide or iodine in situ, in up to 90% isolated yields

method for the synthesis of N-azine sulfoximines by the nucleophilic substitution of azine N-oxides with NH-sulfoximines. The present method works at room temperature with wide functional group compatibility and gives several unprecedented N-azine sulfoximines. The reaction conditions were also found suitable with enantiopure substrates and furnished products without any racemization. It also finds
