Copper-Catalyzed Carboxylation of C-F Bonds with CO2

An effective Cu-catalyzed selective formal carboxylation of C-F bonds with an atmospheric pressure of CO2 is reported. A variety of gem-difluoroalkenes, gem-difluorodienes, and alpha-trifluoro-methyl alkenes show high reactivity and selectivity for this ipso monocarboxylation. Under mild conditions, diverse important alpha-fluoroacrylic acids and alpha,alpha-difluorocarboxylates are obtained in good-to-high yields. Moreover, this operationally simple protocol features good functional group tolerance, is readily scalable, and the resulting products are readily converted into bioactive alpha-fluorinated carbonyl compounds, indicating potential application in biochemistry and drug discovery. Mechanistic studies reveal that fluorinated boronate esters might be vital intermediates in this transformation.

Synthesis of quinazoline-2,4-dione and naphthalimide derivatives as new 5-HT3 receptor antagonists

New potent 5-HT3 receptor antagonists have been designed from the naphthalimide moiety and a quinuclidine heterocycle and the structure-activity relationships are discussed here on the basis of the nature of the substituent on the aromatic system. The biological activity of the compounds was evaluated in binding assays with [3H]BRL-43694 and by inhibition of the Bezold-Jarisch reflex. Compound 22 with a 4-amino substituent was equipotent to the reference compounds. In contrast to the benzamide derivatives, the activity resides essentially in the (R) enantiomer (K(i) = 0.15 ¡À 0.05 nM, ID50 = 1.6 mug/kg/iv) and it is demonstrated that the additional carbonyl group is involved in the inversion of the enantioselectivity of the receptor. Conformational studies of (R)-22 demonstrated the presence of a locked structure with 4 minimal energy conformers which were compared to those of (S)-zacopride. The superimposition of the putative active conformers emphasized the presence of a second polar group in the binding site. The fluorescent properties of the compounds were studied and indicate that (R)-22 and its derivatives may be promising tools for the direct visualization of 5-HT3 receptors.

New Strategies for the Transition-Metal Catalyzed Synthesis of Aliphatic Amines

Transition-metal catalyzed reactions that are able to construct complex aliphatic amines from simple, readily available feedstocks have become a cornerstone of modern synthetic organic chemistry. In light of the ever-increasing importance of aliphatic amines across the range of chemical sciences, this review aims to provide a concise overview of modern transition-metal catalyzed approaches to alkylamine synthesis and their functionalization. Selected examples of amine bond forming reactions include: (a) hydroamination and hydroaminoalkylation, (b) transition-metal catalyzed C(sp3)-H functionalization, and (c) transition-metal catalyzed visible-light-mediated light photoredox catalysis.

Discovery and structure-activity relationship of quinuclidine benzamides as agonists of alpha7 nicotinic acetylcholine receptors

A library of benzamides was tested for alpha7 nicotinic acetylcholine receptor (nAChR) agonist activity using a chimeric receptor in a functional, cell-based, high-throughput assay. From this library, quinuclidine benzamides were found to have alpha7 nAChR agonist activity. The SAR diverged from the activity of this compound class verses the 5-HT3 receptor, a structural homologue of the alpha7 nAChR. PNU-282987, the most potent compound from this series, was also shown to open native alpha7 nAChRs in cultured rat neurons and to reverse an amphetamine-induced gating deficit in rats.

Intriguing case of Pseudo-isomorphism between chiral and racemic crystals of rac- and (S)/(R)2-(1,8-Naphthalimido)-2-quinuclidin-3-yl, and their reactivity toward I2 and IBr

Condensation reactions between 1,8-naphthalic anhydride and racemic 3-aminoquinuclidine or chiral (S) or (R)-(-)-3-aminoquinuclidine allowed preparation of three novel racemic and enantiopure aza-donor ligands, namely NMiABCO (1), (S)NMiABCO (2a), and (R)NMiABCO (2b). Racemic NMiABCO (1) crystallizes in the monoclinic space group P21/c, Z? = 1, while enantiopure (S)NMiABCO (2a) and (R)NMiABCO (2b) crystallize in the chiral monoclinic space group P21, Z? = 2, and show significant pseudocentrosymmetry, being pseudo-isomorphous with racemic NMiABCO (1). Reactivity of both racemic and enantiopure NMiABCO toward iodine and interhalogen IBr was also investigated as a way to remove the pseudoisomorphism, yielding the three new molecular adducts [NMiABCO¡¤I2] (3), [(S)NMiABCO¡¤I2]¡¤xCHCl3 (4), [(S)NMiABCO¡¤IBr]¡¤xCHCl3 (5) and the molecular salt [HNMiABCO][IBr2] (6). Synthesis of complexes 3 and 4 was also carried out in the solid state via kneading and vapor digestion techniques. All compounds were fully characterized via single crystal and powder X-ray diffraction and Raman spectroscopy.
