Phase-transfer catalyzed asymmetric arylacetate alkylation

Phenethyl arylacetates are alkylated under phase-transfer conditions with cinchona catalysts with alkyl halides in high yield with excellent enantioselectivity (84-99% ee) following recrystallization. Cinchonidine (CD) derived catalyst gave the (R)-product and cinchonine (CN) catalyst produced the (S)-product. The phenethyl (PE) ester group is removed, using ammonium formate and catalytic Pd/C, to give alkylated carboxylic acid products in high selectivity. The utility of the approach is demonstrated by a direct synthesis of (S)-naproxen.

Promotion of reaction of N-H bonds with triarylbismuth and cupric acetate

Arylation of a diverse group of N-H containing compounds at room temperature with triarylbismuth and cupric acetate in the presence of a tertiary amine promoter, such as triethylamine or pyridine, is described. This mild and highly efficient procedure, which is based on Barton’s earlier work on the arylation of amines, can be applied to amides, imides, ureas, carbamates, and sulfonamides.

Synthesis and antimicrobial activity of 4H-4-oxoquinolizine derivatives: Consequences of structural modification at the C-8 position

The antibacterial 4H-4-oxoquinolizines were introduced recently to overcome bacterial resistance to fluoroquinolones. They exhibit potent antibacterial activity against Gram-positive, Gram-negative, and anaerobic organisms and are highly active against some quinolone-resistant bacteria including quinolone-resistant MRSA. Preliminary studies indicated that oxoquinolizines possess distinct activity and toxicity profiles as compared with their parent quinolones. In order to develop a potent antibacterial agent with the desired spectrum of activity, good tolerability, and balanced pharmacokinetic profile, we synthesized and evaluated a series of oxoquinolizines with various substituents at the C-8 position. Most compounds tested in this study demonstrated better activity against Gram-positive bacteria than ciprofloxacin and exhibited good susceptibility against ciprofloxacin- and methicillin-resistant S. aureus. While maintaining potent in vitro activity, several compounds showed improved in vivo efficacy over ABT-719 as indicated by the mouse protection test. As an example, the oral ED50 values for the cis-3-amino-4-methylpiperidine analogue 3ss against S. aureus NCTC 10649M, S. pneumoniae ATCC 6303, and E. coli JUHL were 0.8, 2.0, and 1.4 mg/kg, compared to 3.0, 10.0, and 8.3 mg/kg for ABT-719. The current study revealed that the steric and electronic environment conformation, and absolute stereochemistry of the C-8 group are very important to the antibacterial profiles. Structural modifications of the C-8 group provide a useful means to improve the antibacterial activities, physicochemical properties, and pharmacokinetic profiles. Manipulation of the C-8 group also allows us to generate analogues with the desired spectrum of activity, such as analogues that are selective against respiratory pathogens.

High service temperature, self-mendable thermosets networked by isocyanurate rings

A new mending chemistry exhibiting stability at extreme temperatures and holding mechanical properties as well as mechanical stability comparable to widely used engineering plastics is reported here. This mendable thermoset polymer is synthesized using commodity reactants through the formation of an isocyanurate-oxazolidone network which exhibit a high service temperature as shown by their Tg of 270?C and Td of 365?C. We demonstrate that this network polymer is repeatedly self-mendable in the presence of a macroscopic crack, yielding considerable recovery of the polymer’s strength after thermal annealing. This self-mending behavior is derived from a high density of mechano-responsive isocyanurate rings which are introduced as cross-links in the network. After mechanically initiated cycloreversion, the recovery of isocyanurate rings in a solid state is thermally initiated. This research is the first demonstration of an isocyanurate ring as a repairing moiety. We developed a new class of intrinsic self-mendable polymers withstanding high temperatures, which will greatly impact the application of thermoset polymers in the field of structural laminates and electronics packaging.
