Tetrabutylammonium iodide-catalyzed oxidative coupling of enamides with sulfonylhydrazides: synthesis of β-keto-sulfones.
A facile synthetic route towards pharmaceutically interesting β-keto-sulfone derivatives by tetrabutylammonium iodide (TBAI)/tert-butyl hydroperoxide (TBHP) mediated oxidative coupling of readily prepared enamides with economical sulfonylhydrazides is described. The corresponding β-keto-sulfone compounds were obtained in moderate to good yields. The present method is metal-free and base-free an...
متن کاملCyclizations and cycloadditions of acetylenic sulfones on solid supports.
Acetylenic sulfones attached to solid supports by means of ester linkers were employed in a variety of cyclization and cycloaddition reactions, followed by cleavage of the products from the resin by ester hydrolysis or reductive desulfonylation.
متن کاملPhotochemical Reductive Elimination of TetrachloroiodateQII)
In analogy to transition metal complexes, coordination compounds of the main group metals can be also classified according to the electron configuration at the metal. Generally, the main group metals occur in oxidation states with so, s2, s2p2 and s2p4 ground states. Recently, we studied the photolysis of so and s2 systems [l-4]. We now report the first results on the photochemistry of an s2p2 ...
متن کاملRearrangement of β,γ-Unsaturated Esters with Thallium Trinitrate: Synthesis of Indans Bearing a β-Keto Ester Moiety
The indan skeleton is present in a variety of molecules with important biological activity, including the wellknown Indinavir and Aricept. Our research group has investigated approaches to obtain indans from 1,2dihydronaphthalenes, using a thallium(III)-promoted ring contraction reaction. During these studies, we found that a side chain at the double bond has a strong influence in the reaction ...
متن کاملHighly Functionalized 1,2–Diamino Compounds through Reductive Amination of Amino Acid-Derived β–Keto Esters
1,2-Diamine derivatives are valuable building blocks to heterocyclic compounds and important precursors of biologically relevant compounds. In this respect, amino acid-derived β-keto esters are a suitable starting point for the synthesis of β,γ-diamino ester derivatives through a two-step reductive amination procedure with either simple amines or α-amino esters. AcOH and NaBH(3)CN are the addit...
