Palladium‐Catalyzed Oxidative Synthesis of α‐Acetoxylated Enones from Alkynes
We report a palladium-catalyzed oxidative functionalization of alkynes to generate α-acetoxylated enones in one step. A range of functional groups are well-tolerated in this reaction. Mechanistic studies, including the use of (18) O-labeled DMSO, revealed that the ketone oxygen atom in the product originates from DMSO.
متن کاملTetra-N-Butyl ammonium hydroxide mediated one-pot synthesis of pyrano [2, 3-d] pyrimidinone Derivatives
Tetra-N-Butyl Ammonium Hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oC. Current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.In conclusion, we have explo...
متن کاملGuanidinium iodide-catalyzed oxidative α-nitroalkylation of β-ketoamides.
Oxidative nitroalkylation of β-ketoamides and nitroalkanes, mediated by hypoiodide generated from tert-butyl hydrogen peroxide and a catalytic amount of guanidinium iodide, afforded the corresponding α-nitroalkyl-β-ketoamides in up to 97% yield.
متن کاملSynthesis of cyclic enones via direct palladium-catalyzed aerobic dehydrogenation of ketones.
α,β-Unsaturated carbonyl compounds are versatile intermediates in the synthesis of pharmaceuticals and biologically active compounds. Here, we report the discovery and application of Pd(DMSO)(2)(TFA)(2) as a catalyst for direct dehydrogenation of cyclohexanones and other cyclic ketones to the corresponding enones, using O(2) as the oxidant. The substrate scope includes heterocyclic ketones and ...
متن کاملTetrabutylammonium 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...
