Molecularly imprinted nanoparticles to mimic natural enzymes for substrate-selective catalysis
… selective catalysis in hydrolyzing nonactivated alkyl esters, hydrolysis of glycosides, and doing nucleophilic substitution reactions. By taking advantage of templates, we can regulate the active site's size and shape and install different catalytic groups in the right positions near each other …

A hydrogen bonding ortho-directing effect for the iridium catalyzed borylation of NH(t-BOC) aromatics
… praised. Most aromatic substituents, such as alkyl, esters, amides, nitriles, amines, protected phenols and others act as steric obstacles for the iridium catalyst to avoid. This avoidance of appending groups can be reversed into a directed borylation with monophosphine ligands. Alternatively, …

Quarternisation of Benzothiazoles and 1,2,3 - Benzothiadiazoles
… to obtain the halides of these quaternary salts. Alkyl-1,2,3-benzothiadiasolium salts were previously thought to be sulphonium salts. From the results of reductive fission of these salts, it now seems probable that the alkyl group is attached to N-3. Other evidence is also presented in support of …

Formation, Characterization and Stability of Natural Antimicrobial-Cyclodextrin Complexes
… oils and the remaining five compounds are alkyl esters of para-hydroxybenzoic acid. The test compounds were evaluated for aqueous solubility as well as their solubility in an acid-based beverage mixture. The compounds were found to be practically insoluble (< 100 mg/L), very slightly …

Composition of cuticular wax on the leaves of kalanchoe daigremontiana
… primary alcohols, aldehydes, fatty acids, and alkyl esters. Cuticular wax composition in young K. daigremontiana leaves was dominated by triterpenoids, which made up over 70% of the lipid soluble compounds. During leaf ontogenesis, wax composition changed to include a higher proportion of VLCFA …

Reductively triggered internal cyclisation reactions
… investigations have been made on 2-nitrophenyl alkyl esters and a 2,6-dinitrophenylamide prodrug system. Rapid, reductively triggered release of coupled phenols and amines has been observed from the nitro-esters and -amides, respectively. In contrast to amino-amide and hydroxylamino-amide …

Enhancing biodiesel production from soybean oil using ultrasonics
<p>Biodiesel, or fatty acid alkyl ester, is a non-toxic, biodegradable and renewable source of energy. It is mostly produced from vegetable oils. Other sources include animal fat, oils obtained from algae, fungi, bacteria, etc. Esterification of oil with alcohol in the presence of moderate …

Investigating permeation of anti-mycobacterial agents in Mycobacterium tuberculosis and M. tuberculosis-infected macrophages in vitro as a model for early stage tuberculosis drug discovery
… 3-ketofusidic (3-ketoFA or GKFA37), and two C-3 alkyl esters (GKFA16 and GKFA17) as FA prodrugs were utilized in the study. In addition, another chemical class, the less lipophilic benzoxazole-based oxime derivatives were also investigated. Moxifloxacin (MXF), levofloxacin (LVF), bedaquiline …

Lipase catalyzed transesterification of plant oils with dialkyl carbonates
Dialkyl carbonates, especially dimethyl- and diethyl carbonate, have been explored as raw materials for lipase-catalyzed methyl and ethyl ester synthesis and as organic solvents for oilseed extraction. Palm kernels and other potential tropical oilseeds were used as raw materials for this study. The …
