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.

A short entry to enantiopure 2-substituted 1,4-benzodioxanes by efficient resolution methods

(R)-1,4-Benzodioxane-2-carboxilic acid (R)-1 was obtained by resolution of the racemic acid 1 with stoichiometric or nonstoichiometric (+)- dehydroabietylamine (+)-2 in high chemical yield and enantiomeric excess. (S)-1 was isolated from the mother liquors of the crystallisation of (R)-1¡¤(+)-2 and its enantiomeric excess maximised by recrystallisation procedures involving a precipitation under kinetic control or, alternatively, by conversion into the methyl ester followed by a single crystallisation. The different mechanisms of the two S enrichments is well explained by the binary phase diagrams of the acid and of the ester, which show that the former is a racemic compound, whereas the latter a conglomerate. The DSC analyses were extended to 2-hydroxymethyl- and 2-mesyloxymethyl-1,4-benzodioxane, establishing that the alcohol forms a racemic compound, while its mesyl ester a conglomerate. On the basis of these results, different resolution strategies can be designed to obtain useful homochiral 2-substituted 1,4-benzodioxanes coupling the resolution of 1 via diastereomeric salt formation with the enantiomeric enrichments by recrystallisations, preferably of its conglomerate forming derivatives.

Highly efficient resolutions of 1,4-benzodioxane-2-carboxylic acid with para substituted 1-phenylethylamines

The salts of (S)- and (R)-1,4-benzodioxane-2-carboxylic acid with eight (S)-1-arylethylamines were prepared. The determination of their melting points and of their solubilities in alcohol solvents revealed large differences between the diastereomeric benzodioxanecarboxylates of (S)-1-(p-nitrophenyl)ethylamine and of (S)-1-(p-methylphenyl)ethylamine. Therefore, these latter amines were selected to resolve (¡À)-1,4-benzodioxane-2-carboxylic acid by diastereoselective crystallization finding that both of them display a very high resolution ability for such a substrate, which contrasts with the null efficiency of unsubstituted 1-phenylethylamine. These results are consistent with DSC evidences, which indicated that the two successfully resolved diastereomeric systems are binary mixtures exhibiting a eutectic with a high content of the more soluble diastereomeric salt. The new procedures can advantageously replace the two resolutions we had previously reported, that of the same acid with dehydroabietylamine and that of glycerol acetonide, a precursor of 1,4-benzodioxane-2-carboxylic acid, with 1-phenylethylamine.

Heterocycle-peptide hybrid compounds. Aminotriazole-containing agonists of the thrombin receptor (PAR-1)

The thrombin receptor PAR-1 is activated by alpha-thrombin to stimulate cells, including platelets, through the tethered-ligand sequence SFLLRN. We have discovered a novel series of heterocycle-peptide hybrids comprised of a tripeptide segment, such as Cha-Arg-Phe, and an N-terminal heterocyclic group, many of which behave as full PAR-1 agonists. Certain compounds with an aminotriazole group, such as 4 and 16, are nearly as potent as SFLLRN-NH2 in inducing platelet aggregation. Also, some arylethenoyl ‘N-capped’ compounds, such as 52 and 57, exhibit mixed PAR-1 agonist-antagonist activity.

Ligand-Accelerated Iron Photocatalysis Enabling Decarboxylative Alkylation of Heteroarenes

A mild, practical protocol for the decarboxylative alkylation of heteroarenes has been accomplished via iron photocatalysis. A diverse range of carboxylic acids readily undergo oxidative decarboxylation and then couple with a broad array of heteroarenes in this transformation. The photoexcited state lifetimes of iron complexes are typically much shorter than those of iridium and ruthenium complexes. Here we describe our effort on iron photocatalysis by utilizing the intramolecular charge transfer pathway of iron-carboxylate complexes.

Compound C14 ((3-(4-bromophenyl)-5-(2-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)(2,3- dihydrobenzo[b][1,4]dioxin-6-yl)methanone) showed the most potent biological activity against B-RafV600E (IC50 = 0.11 muM) and WM266.4 human melanoma cell line (GI50 = 0.58 muM), being comparable with the positive control Erlotinib and more potent than our previous best compound, while D10 ((2,3-dihydrobenzo[b][1,4]dioxin-2-yl)(5-(3- fluorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)methanone) performed the best in the D series (IC50 = 1.70 muM; GI50 = 1.45 muM). The docking simulation was performed to analyze the probable binding models and poses and the QSAR model was built for reasonable design of B-Raf inhibitors in future. The introduction of 2,3-dihydrobenzo[b][1,4]dioxin structure reinforced the combination of our compounds and the receptor, resulting in progress of bioactivity.
