Development of an Imine Chaperone for Selective C-H Functionalization of Alcohols via Radical Relay

The design of a radical relay chaperone to promote selective C-H functionalizations is described. A saccharin-based imine was found to be uniquely suited to effect C-H amination of alcohols via an in situ generated hemiaminal. This radical chaperone facilitates the mild generation of an N-centered radical while also directing its regioselective H atom transfer (HAT) to the beta carbon of an alcohol. Upon beta C-H halogenation, aminocyclization, and reductive cleavage, an NH2 is formally added vicinal to an alcohol. The development, synthetic utility, and chemo-, regio-, and stereoselectivity of this imine chaperone-mediated C-H amination is presented herein.

Targeted fluorination with the fluoride ion by manganese-catalyzed decarboxylation

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. Nucleophile first: An efficient manganese porphyrin catalyzed decarboxylative fluorination reaction based on a nucleophilic fluorine source is described. The potential of the described method for use in PET imaging has been demonstrated by the successful 18F labeling of various aliphatic carboxylic acids, representing the first decarboxylative 18F labeling method with no-carrier-added [18F]fluoride.

An Efficient Synthesis of Polysubstituted Pyridines via C sp 3 -H Oxidation and C-S Cleavage of Dimethyl Sulfoxide

An expedient cleavage of the C-S bond of dimethyl sulfoxide (DMSO) has been developed for the preparation of substituted pyridines from ketones. In this transformation, the co-product formic acid was formed from ammonium formate, which acted as an important catalyst for the reaction. Notably, this transformation exhibited a broad substrate scope towards a wide variety of different ketones to give the corresponding substituted pyridines in high yields. Mechanistic studies suggested that dimethyl sulfoxide delivered a methylene fragment, which was subsequently captured in situ to give a pyridine.

3-Phenylpropanoic acid-based phosphotyrosine (pTyr) mimetics: Hit evolution to a novel orally active protein tyrosine phosphatase 1B (PTP1B) inhibitor

Protein tyrosine phosphatase 1B (PTP1B) is a promising therapeutic target for type 2 diabetes. Herein, we report the evolution of a previously identified 3-phenylpropanoic acid-based PTP1B inhibitor to an orally active lead compound. A series of 3-phenylpropanoic acid-based PTP1B inhibitors were synthesized, and three of them, 3-(4-(9H-carbazol-9-yl)phenyl)-5-(3,5-di-tert-butyl-4- methoxyphenyl)-5-oxopentanoic acid (9), 3-(4-(9H-carbazol-9-yl)phenyl)-5- (4?-bromo-[1,1?-biphenyl]-4-yl)-5-oxopentanoic acid (10) and 3-(4-(9H-carbazol-9-yl)-2-fluorophenyl)-5-(4-cyclohexylphenyl)-5-oxopentanoic acid (16), showed IC50 values at sub-micromolar level. Further in vivo evaluation indicated the sodium salt of 9 not only exhibited significant insulin-sensitizing and hypoglycemia effects, but also decreased the serum levels of triglyceride and total cholesterol in high-fat-diet-induced insulin resistance model mice. Preliminary in vivo pharmacokinetic studies on the sodium salt of 9 revealed its pharmacokinetic profile after oral administration in rats. These results provide proof-of-concept for the dual effects of PTP1B inhibitors on both glucose and lipid metabolisms. A sincere form of flattery: A novel protein tyrosine phosphatase 1B (PTP1B) inhibitor with a 3-phenylpropanoic acid moiety as a phosphotyrosine (pTyr) mimetic was optimized to provide an orally active lead compound with an IC50 value of 0.40 muM against PTP1B and more notably that displayed significant in vivo activity in a murine insulin resistance model.

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

Metal-free, ionic liquid-mediated synthesis of functionalized quinolines

An expedient and metal-free synthetic protocol for construction of substituted quinolines has been developed from anilines and phenylacetaldehydes using imidazolium cation-based ionic liquids as the reaction medium. Mechanistic analysis indicated that the reaction occurs through C-C and C-N bond formation to produce isolable 2,3-disubstituted quinoline intermediates, which undergo C-C bond cleavage to produce 3-substituted quinolines. The reaction proceeds smoothly with a range of functionalities in good to excellent yields. Advantages of this protocol include metal-free, environmentally friendly, recyclable reaction media, higher yields and shorter reaction times, and thus is promising for the efficient combinatorial synthesis of structurally diverse 2,3-disubstituted and 3-substituted quinolines.
