One-Pot Sequential Photoredox Chemistry and Asymmetric Transfer Hydrogenation with a Single Catalyst

A sequential process is reported, in which different photoredox reactions are placed in sequence with asymmetric transfer hydrogenations of aryl ketones to provide a diverse set of chiral alcohols with enantioselectivities of up to 99 % ee. The method relies on a single chiral-at-metal catalyst which is added at the beginning of the two step sequence and only a final purification of the reaction product is required.

Staudinger reactions of unsymmetrical cyclic ketenes: A synthetically useful approach to spiro beta-lactams and derivatives. Reaction mechanism and theoretical studies

An efficient and operationally simple synthesis of tetrahydrofuran-derived spiro-beta-lactams using the ketene-imine cycloaddition route is described. Also the preparation of spiro-N-sulfonyl-beta-lactam derivatives, which are analogs of monobactams, is reported. As far as we know, this is the first time that an unsymmetrical cyclic ketene is used in a Staudinger-type reaction. The experimental evidence suggests the involvement of a ketene derived from the acyl chloride precursor in the reaction. High-level ab initio calculations have been performed in order to get insight into the electronic effects controlling the stereochemical outcome of the reactions.

Heterocycles [h]-Fused onto 4-oxoquinoline-3-carboxylic acid, III.1 Facile synthesis and antitumor activity of model heterocycles [a]-fused onto pyrido[2,3-f]quinoxaline-3-carboxylic acids

Direct interaction between 7-chloro-1-cyclopropyl-6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid and each of (S)-proline, (2S,4R)-4-hydroxyproline and (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid in hot aqueous ethanolic NaHCO3 yielded the corresponding optically pure N-(4-oxoquinolin-7-yl)-a-amino acids. The latter derivatives underwent reductive lactamization upon treatment with Na2S2O4 in aqueous ethanol to afford moderate yields of the respective pyrido[2,3-f]quinoxaline-3-carboxylic acid [fused]- to tetrahydropyrrolo[1,2-a]-, tetrahydrohydroxylpyrrolo[1,2-a]-and tetrahydroisoquinolino[2,3-a]heterocyclics 10-12, respectively. The antitumor activity against four human tumor cell lines showed that 10-12 displayed high levels of cytotoxicity as compared with Cisplatin. Interestingly, these compounds were more potent against breast carcinoma cell lines (MCF-7 and T-47D) than the lymphoid origin tumor cell lines (Jurkat and BHL-89). In particular, the (S)-proline derivative 10 exhibited preferential cytotoxicity to adherent cells (IC50 = 0.5 muM), indicative of better potential in blocking the growth of solid tumors rather than the disseminated ones.

Photocatalytic oxidative C-C bond formation

This chapter summarizes some important examples of carbon-carbon bond-forming reactions at the alpha-position of tertiary amines using photoredox catalysis. The photocatalytic single-electron oxidation of tertiary amines leads to the generation of an amine radical cation, from which two highly reactive and synthetically useful intermediates, iminium ions and alpha-aminoalkyl radicals, can be produced. Iminium ion intermediates, being electrophilic in nature, react with a range of carbon nucleophiles forming new carbon-carbon bonds. On the other hand, the alpha-aminoalkyl radical, an electron-rich radical, adds efficiently to electron-deficient unsaturated systems resulting in carbon-carbon bond-forming reactions. This chapter also highlights some examples of carbon-carbon bond-forming reaction by nucleophilic/radical addition to photocatalytically generated arene radical cations.

Degenerate Transesterification of 3,5-Dimethylphenolate/3,5-Dimethylphenyl Esters in Weakly Polar, Aprotic Solvents. Reactions of Aggregates and Complex-Induced Proximity Effects

The rates of exchange of the 3,5-dimethylphenolate ion between lithium 3,5-dimethylphenolate-d6 and a series of 3,5-dimethylphenyl esters have been determined in the weakly polar, aprotic solvents dioxolane, dimethoxyethane (DME), tetrahydrofuran (THF), and pyridine. The esters include the propionate, butyrate, methoxyacctate, beta-methoxypropionate, 4-methoxybutyrate, 2-tetrahydrofuroate, 2-furoate, (N,N-dimethylamino)acetate, (methylthio)acetate, 2- and 4-pyridine-carboxylates, 2-pyridylacetate, 4-pyridylacetate, phenylacetate, andp-methoxy-,p-chloro-, and p-(trifluoromethyl)phenylacetates. The rates and kinetic orders of the reactions of 3,5-dimethylphenyl propionate in various solvents at 35C gave the following second-order rate constants (104k2, L mol-1 sec-1) for the following major aggregate species: THF tetramer, 6.5; DME tetramer, 3.3 (40C); dioxolane, 13, hexamer, 71; pyridine tetramer, 2.2, dimer, 29. For 3,5-dimethylphenyl beta-methoxypropionate, the order of reactivity is dioxolane > DME > THF. These results are interpreted in terms of a preequilibrium in which a solvent on lithium in the tetramer is replaced by the ester. The rates of transesterification have been compared with the rates of hydrolysis in 30% aqueous ethanol for the above series of esters. Those esters that have a second Lewis base center proximal to the ester function show significantly increased reactivity in transesterification, which is attributed to a complex-induced proximity effect.

Synthesis and antimuscarinic properties of quinuclidin-3-yl 1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives as novel muscarinic receptor antagonists

In the course of continuing efforts to develop potent and bladder-selective muscarinic M3 receptor antagonists, quinuclidin-3-yl 1-aryl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives and related compounds were designed as conformationally restricted analogues of quinuclidin-3-yl benzhydrylcarbamate (8). Binding assays with rat muscarinic receptor subtypes revealed that the quinuclidin-3-yl 1-aryl-1,2,3,4- tetrahydroisoquinoline-2-carboxylate derivatives showed high affinities for the M3 receptor, and selectivity for the M3 receptor over the M2 receptor. Of these derivatives, (+)-(1S,3’R)-quinuclidin-3′-yl 1-phenyl-l,2,3,4-tetrahydroisoquinoline-2-carboxylate monohydrochloride (9b) exhibited almost the same inhibitory activity against bladder contraction to that of oxybutynin (1), and more than 10-fold selectivity for bladder contraction versus salivary secretion, demonstrating that 9b may be useful for the treatment of symptoms associated with overactive bladder without having side effects such as dry mouth.
