Abstract An eco‐friendly and facile three‐component reaction for the synthesis of 2‐amino‐4 H ‐pyran tetrahydrobenzo[ b ]pyran derivatives is established using agro‐waste based Water Extract Muskmelon Fruit Shell Ash (WEMFSA) as a catalyst. The present method offers several advantages such efficient, mild condition, simple product isolation economic approach at room temperature in absence an external base or ligand/catalyst/additives. Thus, this very good alternative to existing protocols, because non‐hazardous catalyst condition use. fruit dried shells underwent thermal treatment followed by deionised water soak gave WEMFSA catalytic media. It notable that, found be clean high yielding target filtration after mixture dilution with analytical pure form was obtained recrystallization absolute ethanol. synthesized products are characterized various spectroscopic methods FT‐IR, 1 H‐, 13 C‐NMR mass spectrometry techniques.

The visible-light-promoted catalyst-free condition has been demonstrated for self- and cross-coupling reactions of thiols in an ambient atmosphere. Further, synthesis β-hydroxysulfides is accomplished under very mild conditions involving the formation electron donor-acceptor (EDA) complex between a disulfide alkene. However, direct reaction thiol with alkene via thiol-oxygen co-oxidation (TOCO) failed to produce desired compounds high yields. protocol was successful several aryl alkyl disulfides. required aromatic unit on fragment, which supports EDA during course reaction. approaches presented this paper coupling are unique do not require toxic organic or metal catalysts.

This is the first report on synthesis and characterization of N-iodo sulfoximines. The was designed as a room temperature one-pot cascade reaction from readily available sulfides starting compounds, converted into sulfoximines by with ammonium carbonate (diacetoxyiodo)benzene, followed iodination N-iodosuccinimide or iodine in situ, up to 90% isolated yields, also at multigram scale. Iodination aryls sulfoximines, oxidation, conversion N-SCF3 congeners have been demonstrated.
