Light-Driven Intramolecular C?N Cross-Coupling via a Long-Lived Photoactive Photoisomer Complex

Reported herein is a visible-light-driven intramolecular C?N cross-coupling reaction under mild reaction conditions (metal- and photocatalyst-free, at room temperature) via a long-lived photoactive photoisomer complex. This strategy was used to rapidly prepare the N-substituted polycyclic quinazolinone derivatives with a broad substrate scope (>50 examples) and further exploited to synthesize the natural products tryptanthrin, rutaecarpine, and their analogues. The success of gram-scale synthesis and solar-driven transformation, as well as promising tumor-suppressing biological activity, proves the potential of this strategy for practical applications. Mechanistic investigations, including control experiments, DFT calculations, UV-vis spectroscopy, EPR, and X-ray single-crystal structure of the key intermediate, provides insight into the mechanism.

C-H functionalization of cyclic amines: Redox-annulations with alpha,beta-unsaturated carbonyl compounds

Cyclic amines such as pyrrolidine and 1,2,3,4-tetrahydroisoquinoline undergo redox-annulations with alpha,beta-unsaturated aldehydes and ketones. Carboxylic acid promoted generation of a conjugated azomethine ylide is followed by 6pi-electrocylization, and, in some cases, tautomerization. The resulting ring-fused pyrrolines are readily oxidized to the corresponding pyrroles or reduced to pyrrolidines. This journal is

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.

Highly efficient heterogeneous aerobic cross-dehydrogenative coupling via C-H functionalization of tertiary amines using a nanoporous gold skeleton catalyst

We report for the first time that zero-valent nanoporous gold (AuNPore) is a robust and green heterogeneous catalyst for alpha-C-H functionalization of various tertiary amines. AuNPore combines with molecular oxygen at 80 C or tert-butyl hydrogen peroxide at room temperature and catalyses the heterogeneous cross-dehydrogenative coupling (CDC) reaction efficiently to afford the corresponding C-C and C-heteroatom coupling products in good to excellent yields with excellent reusability.

Synthesis of 2-(2,3-dimethoxyphenyl)-4-(aminomethyl)imidazole analogues and their binding affinities for dopamine D2 and D3 receptors

A series of 2-(2,3-dimethoxyphenyl)-4-(aminomethyl)imidazole derivatives was prepared and their affinity for dopamine D2 and D3 receptors was measured using in vitro binding assays. Several oxadiazole analogues were also prepared and tested for their affinity for dopamine D2 and D3 receptors. The results of receptor binding studies indicated that the incorporation of an imidazole moiety between the phenyl ring and the basic nitrogen did not significantly increase the selectivity for dopamine D3 receptors, whereas the incorporation of an oxadiazole at the same region resulted in a total loss of affinity for both dopamine receptor subtype binding sites. The most selective compound in this series is 2-(5-bromo-2,3-dimethoxyphenyl)-4-(6,7-dimethoxy-1,2,3, 4-tetrahydroisoquinolinomethyl)imidazole (5i), which has a D3 receptor affinity of 21 nM and a 7-fold selectivity for D3 versus D2 receptors. The binding affinity for sigma1 and sigma2 receptors was also measured, and the results showed that several analogues were selective sigma1 receptor ligands.

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.
