Visible-Light-Mediated Decarboxylative Radical Additions to Vinyl Boronic Esters: Rapid Access to gamma-Amino Boronic Esters

The synthesis of alkyl boronic esters by direct decarboxylative radical addition of carboxylic acids to vinyl boronic esters is described. The reaction proceeds under mild photoredox catalysis and involves an unprecedented single-electron reduction of an alpha-boryl radical intermediate to the corresponding anion. The reaction is amenable to a diverse range of substrates, including alpha-amino, alpha-oxy, and alkyl carboxylic acids, thus providing a novel method to rapidly access boron-containing molecules of potential biological importance.

Asymmetric hydrogenation of furan-containing ketones over tartaric acid-modified Raney nickel catalyst

The hydrogenation of beta-keto esters containing a furan unit at the conjugated position to the beta-carbonyl group was carried out over a chiral heterogeneous catalyst, tartaric acid-modified Raney nickel. The hydrogenation first proceeds at the carbonyl to give optically active alcohols, but a simple substrate undergoes further hydrogenation of the furan part to produce a diastereomeric mixture of alcohols having a tetrahydrofuran moiety. This over-reduction was efficiently suppressed by substitutions of a substituent at the furan part. The optical yield at the hydroxy group is in the range of 40-90%.

Structure-based design of new dihydrofolate reductase antibacterial agents: 7-(benzimidazol-1-yl)-2,4-diaminoquinazolines

A new series of dihydrofolate reductase (DHFR) inhibitors, the 7-(benzimidazol-1-yl)-2,4-diaminoquinazolines, were designed and optimized for antibacterial potency and enzyme selectivity. The most potent inhibitors in this series contained a five-membered heterocycle at the 2-position of the benzimidazole, leading to highly potent and selective compounds that exploit the differences in the size of a binding pocket adjacent to the NADPH cofactor between the bacterial and human DHFR enzymes. Typical of these compounds is 7-((2-thiazol-2-yl)benzimidazol-1-yl)-2,4 diaminoquinazoline, which is a potent inhibitor of S. aureus DHFR (Ki = 0.002 nM) with 46700-fold selectivity over human DHFR. This compound also has high antibacterial potency on Gram-positive bacteria with an MIC versus wild type S. aureus of 0.0125 mug/mL and a MIC versus trimethoprim-resistant S. aureus of 0.25 mug/mL. In vivo efficacy versus a S. aureus septicemia was demonstrated, highlighting the potential of this new series.

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.

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 of highly functionalized polycyclic quinoxaline derivatives using visible-light photoredox catalysis

A mild and facile method for preparing highly functionalized pyrrolo[1,2-a]quinoxalines and other nitrogenrich heterocycles, each containing a quinoxaline core or an analogue thereof, has been developed. The novel method features a visible-light-induced decarboxylative radical coupling of ortho-substituted arylisocyanides and radicals generated from phenyliodine(III) dicarboxylate reagents and exhibits excellent functional group compatibility. A wide range of quinoxaline heterocycles have been prepared. Finally, a telescoped preparation of these polycyclic compounds by integration of the in-line isocyanide formation and photochemical cyclization has been established in a three-step continuousflow system.
