Phosphazene Base tBu-P4 Catalyzed Methoxy–Alkoxy Exchange Reaction on (Hetero)Arenes

The organic superbase tBu-P4 catalyzes methoxy-alkoxy exchange reactions on (hetero)arenes with alcohols. The catalytic reaction proceeded efficiently with electron-deficient methoxy(hetero)arenes as well as with a variety of alcohols, including 3-amino-1-propanol, β-citronellol, menthol, and cholesterol. An intramolecular version of this reaction furnished six- and seven-membered ring compounds.

Synthesis and antimicrobial studies of new antibacterial azo-compounds active against staphylococcus aureus and listeria monocytogenes

Some novel (phenyl-diazenyl)phenols (4a–m) were designed and synthesized to be evaluated for their antibacterial activity. Starting from an active previously-synthesized azobenzene chosen as lead compound, we introduced some modifications and optimization of the structure, in order to improve solubility and drug conveyance. Structures of all newly-synthesized compounds were confirmed by 1H nuclear magnetic resonance (NMR), mass spectrometry, and UV-Vis spectroscopy. Antibacterial activity of the new compounds was tested with the dilution method against the bacteria strains Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa PAO1. All the compounds were selectively active against Gram-positive bacteria. In particular, compounds 4d, 4h, and 4i showed the highest activity against S. aureus and Listeria monocytogenes, reaching remarkable MIC100 values of 4 μg/mL and 8 μg/mL. The relationship between antimicrobial activity and compound structure has suggested that the presence of hydroxyl groups seems to be essential for antimicrobial activity of phenolic compounds.

Electronic dependence of C-O reductive elimination from palladium (aryl)neopentoxide complexes

Thermal decomposition of the palladium (aryl)neopentoxide complexes [P-P]Pd(Ar)OCH2CMe3 [P-P =Tol-BINAP or BINAP; Ar p-C6H4CHO (1b), p-C6H4COPh (1c), p-C6H4NO2 (1d), o-C6H4NO2 (1e), o-C6H4CN (1F)] possessing substituents on the palladium-bound aryl group suitable for delocalization of negative charge led to quantitative (≤95%) formation of aryl ether without detectable β-hydride elimination. Thermal decomposition of 1b-f obeyed first-order kinetics, and the rate of reductive elimination decreased in the order o-NO2 > p-NO2 > p-CHO > p-COPh > o-CN. Conversely, thermal decomposition of the related derivatives [P-P]Pd(Ar)OCH2CMe3 [P-P = Tol-BINAP or BINAP; Ar p-C6H4Cl (1g), m-C6H4NO2 (1h), m-C6H4CN (1i)] which did not possess a resonance stabilizing group on the palladium-bound aryl group led to no detectable formation of aryl ether. These and related data point to the buildup of negative charge in the palladium-bound aryl group in the transition state for C-O reductive elimination and are consistent with a mechanism initiated by inner-sphere nucleophilic attack of the alkoxide ligand at the ipso-carbon atom of the palladium-bound aryl group through a zwitterionic Meisenheimer-type intermediate or transition state.

Studies on antihyperlipidemic agents. III. Synthesis and biological activities of 2-chloro-3-arylpropionic acids containing a quarternary carbon atom

A series of 2-chloro-3-(4-alkoxyphenyl)propionic acids containing a quarternary carbon atom in the alkoxy moiety was prepared and the hypolipidemic and hypoglycemic activities were evaluated. Of the 18 compounds synthesized, ethyl 2-chloro-3-[4-(2-methyl-2-phenylpropyloxy)phenyl]propionate was the best with respect to biological activity and toxicity. Its functional derivatives and optically resolved enantiomers were also prepared. Structure-activity relationships are discussed briefly.
