Compared to the alpha-functionalization of aldehydes, ketones, even esters, the direct alpha-modification of amides is still a challenge because of the low acidity of alpha-CH groups. The alpha-functionalization of N?H (primary and secondary) amides, containing both an unactived alpha-C?H bond and a competitively active N?H bond, remains elusive. Shown herein is the general and efficient oxidative alpha-oxyamination and hydroxylation of aliphatic amides including secondary N?H amides. This transition-metal-free chemistry with high chemoselectivity provides an efficient approach to alpha-hydroxy amides. This oxidative protocol significantly enables the selective functionalization of inert alpha-C?H bonds with the complete preservation of active N?H bond.

Organic molecules bearing acetoxy moieties are important functionalities in natural products, drugs, and agricultural chemicals. Synthesis of such molecules via transition metal-catalyzed C-O bond formation can be achieved in the presence of a carefully chosen directing group to alleviate the challenges associated with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the carboxylate followed by rapid decarboxylation and oxidation by Cu(OAc)2

We describe the first catalytic decarboxylative fluorination reaction based on the nucleophilic fluoride ion. The reported method allows the facile replacement of various aliphatic carboxylic acid groups with fluorine. Moreover, the potential of this method for PET imaging has been demonstrated by the successful 18F labeling of a variety of carboxylic acids with radiochemical conversions up to 50-%, representing a targeted decarboxylative 18F labeling method with no-carrier-added [18F]fluoride. Mechanistic probes suggest that the reaction proceeds through the interaction of the manganese catalyst with iodine(III) carboxylates formed in situ from iodosylbenzene and the carboxylic acid substrates.

An operationally simple method is disclosed for the decarboxylative cyanation of aliphatic carboxylic acids at room temperature. Riboflavin tetraacetate, which is an inexpensive organic photocatalyst, promotes the oxidation of carboxylic acids upon visible-light activation. After decarboxylation, the generated radicals are trapped by TsCN, yielding the desired nitriles without any further additive, in a redox-neutral process. Importantly, this protocol can be adapted to flow conditions.

Alkynes and nitriles are important functional groups that serve as versatile building blocks in organic synthesis and find applications in material and medicinal sciences. A convenient and straightforward access to both classes of compounds under mild conditions is, therefore, highly desirable. Herein, we disclose the decarb-oxylative alkynylation and cyanation of broadly available carboxylic acids using photoredox catalysis and hyper-valent iodine reagents. Choices of both catalysts and reagents were crucial. Computational and experimental studies revealed two different possible mechanisms that are dictated by the oxidation potential of the reagents: radical for alkynylation, ionic for cyanation.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Herein, we report the photocatalytic decarboxylative alkenylation reactions of N-(acyloxy)phthalimide derived from alpha-amino and alpha-hydroxy acids with 1,1-diarylethene, and with cinnamic acid derivatives through double decarboxylation, using sodium iodide and triphenylphosphine as redox catalysts. The reaction proceeds under mild irradiation conditions with visible blue light (440 nm or 456 nm) in an acetone solvent without recourse to transition-metal or organic dye based photoredox catalysts. The reaction proceeds via photoactivation of a transiently self-assembled chromophore from N-(acyloxy)phthalimide and NaI/PPh3. Solvation plays a crucial role in the reactivity.

A series of peptides containing 1,4-benzodioxane nucleus were attempted to synthesize by conventional as well as green techniques like microwave-assisted and sonication, using dicyclohexylcarbodiimide (DCC) as a coupling reagent and triethylamine as a base. Sonication has proved to be the efficient method for the synthesis of the title compounds. All the compounds were characterized by FTIR, 1H NMR and Mass spectral studies. They were evaluated for their insecticidal and anthelmintic activities. All the compounds showed moderate anthelmintic activity as compared to the standard drug mebendazole. However, the compounds exhibited potent insecticidal activity, the most potent being 1,4-benzodioxane-2-carboxyl-phenylalaninetryptophan- methyl ester as compared to the standard, chloropyrifos.
