Reactions of pyridines and imidazoles with substituted phenyl acetates and trifluoroacetates have been studied in acetonitrile and in water-acetonitrile containing 0.56 mol/dm3 of water.The water isotope effects, steric effects, the effect of water in the reaction medium, and the derived Broensted beta and Hammett rho values have been used as mechanistic criteria.Pyridines and imidazoles catalyse the hydrolysis of phenyl trifluoroacetates by general base catalysis while imidazole acts as nucleophile toward 4-nitrophenyl and 2,4-dinitrophenyl acetates.As indicated by the second-order dependence on amine concentration beside the first-order term in amine, the reaction of imidazole exhibits general base catalysis in the case of both phenyl acetates and phenyl trifluoroacetates.This reaction obviously is general base-catalysed nucleophilic reaction of imidazole.The activation parameters DeltaH* and DeltaS* derived for the reactions of pyridine and imidazole with 4-nitrophenyl trifluoroacetate and for the reaction of imidazole with 4-nitrophenyl acetate are consistent with the proposed reaction mechanisms.

In this paper we present experimental results for the optical dichroism of ultra-thin layers of an epitropic liquid crystal, 2,6-lutidine, on a carbonized quartz substrate. The carbon layer consists of carbon chains with an orientation perpendicular to the substrate surface. It significantly enhances the orientational order of the lutidine layers adjacent to the surface. A two-fold increase of the orientational order parameter S for 2,6-lutidine (from 0.22 to 0.45) has been measured due to the influence of the carbon layer. The inclusion of nitrogen atoms (nN = 7%) into the carbon film leads to a further increase of S from 0.45 to 0.65.

Palladium-catalyzed site selective arylation reactions of both sp2 and benzylic sp3 sites on azine and diazine N-oxide substrates are described that occur in good to excellent yield and with complete selectivity for reaction at the desired position. These studies have uncovered the need to properly control the metal to ligand ratio in sp2 arylation and necessitated a complete reinvestigation of all reaction parameters for sp3 arylation. From these studies, the choice of base emerged as a pivotal component for site selectivity, pointing to its intimate involvement in the mechanism of direct arylation. These site selective reactions have been validated in both divergent and sequential derivatizations of heterocyclic compounds represent an attractive alternative to other routes to this class of molecule.

A fluoro derivative can be produced by reacting a hydroxy derivative with sulfuryl fluoride (SO2F2) in the presence of an organic base or in the presence of an organic base and a salt or complex composed of an organic base and hydrogen fluoride. This process enables to advantageously produce an optically active fluoro derivative (e.g., a 4-fluoroproline derivative, a 2′-deoxy-2′-fluorouridine derivative and an optically active alpha-fluorocarboxylate ester derivative) which is an important intermediate for the production of a pharmaceutical or agricultural agent or an optical material, even in large quantity without using a perfluoroalkanesulfonyl fluoride which is undesirable for industrial applications.

Starting from a formula of Gaw and Scott, we show by a scaling argument that the volume-composition isotherm of a binary liquid mixture at its consolute temperature should be of the same algebraic degree at the consolute point as the volume-composition coexistence curve and , by continuity, tangent to it there.Our data on 2,4-lutidine + water, and our data together with those of Woermann and Sarholz on isobutyric acid + water, show conspicuously the non-classical vanishing of the curvature of the volume-composition critical isotherm at the consulte point.The predicted tangency of the critical isotherm and coexistence curve is confirmed for isobutyric acid + water within the uncertainties in the estimates.

The degradation of 2-amino-2-methyl-1-propanol (AMP) has been investigated in the presence of oxygen. AMP was not stable and the overall degradation rate of AMP was close to that of Nmethyldiethanolamine (MDEA) under identical conditions. The primary degradation products identified by GC-MS were acetone, 2,4-lutidine and 4,4-dimethyl-2-oxazolidinone. The oxidative degradation rates of AMP strongly depended upon oxygen partial pressure. The effect of temperature on the overall degradation rates was also measured. No significant catalytic effect was observed when 0.1mM ferrous oxalate (Fe C2O4) and 0.1mM copper sulphate (CuSO4) were added into the AMP solutions, respectively, and the degradation rates of AMP show a weak dependence on a radical initiator. Carbon dioxide (CO2) was found to speed up the overall degradation rate of AMP.

Class D beta-lactamases represent a growing and diverse class of penicillin-inactivating enzymes that are usually resistant to commercial beta-lactamase inhibitors. As many such enzymes are found in multi-drug resistant (MDR) Acinetobacter baumannii and Pseudomonas aeruginosa, novel beta-lactamase inhibitors are urgently needed. Five unique 6-alkylidene-2?-substituted penicillanic acid sulfones (1-5) were synthesized and tested against OXA-24, a clinically important beta-lactamase that inactivates carbapenems and is found in A. baumannii. Based upon the roles Tyr112 and Met223 play in the OXA-24 beta-lactamase, we also engineered two variants (Tyr112Ala and Tyr112Ala,Met223Ala) to test the hypothesis that the hydrophobic tunnel formed by these residues influences inhibitor recognition. IC50 values against OXA-24 and two OXA-24 beta-lactamase variants ranged from 10 ± 1 (4 vs WT) to 338 ± 20 nM (5 vs Tyr112Ala, Met223Ala). Compound 4 possessed the lowest Ki (500 ± 80 nM vs WT), and 1 possessed the highest inactivation efficiency (kinact/ Ki = 0.21 ± 0.02 muM-1 s-1). Electrospray ionization mass spectrometry revealed a single covalent adduct, suggesting the formation of an acyl-enzyme intermediate. X-ray structures of OXA-24 complexed to four inhibitors (2.0-2.6 A) reveal the formation of stable bicyclic aromatic intermediates with their carbonyl oxygen in the oxyanion hole. These data provide the first structural evidence that 6-alkylidene-2?-substituted penicillin sulfones are effective mechanism-based inactivators of class D beta-lactamases. Their unique chemistry makes them developmental candidates. Mechanisms for class D hydrolysis and inhibition are discussed, and a pathway for the evolution of the BlaR1 sensor of Staphylococcus aureus to the class D beta-lactamases is proposed.
