In accordance with the aforementioned technique, the reaction of L-ascorbic acid or D-araboascorbic acid of formula IIa or IIb with hydrogen chloride or hydrogen bromide is ideally carried out in solution in a lower alkanecarboxylic acid (e.g. formic acid, acetic acid, propionic acid etc). ...

scope by systematically lifting or altering these reaction rules. We note that such biases are also present in seemingly unbiased enhanced sampling techniques (consider, for instance, the choice of velocities for the nanoreactor38or the choice of collective variables in metadynamics78). However, such ...
This disclosure is intended to describe for a direct amidation reaction with an amine, simple operation, the catalyst activation method at low temperature of the carboxylic acid for organic reactions, in particular. The method involves the use of ortho-substituted aryl boronic acid of formula (I)...

Chemical reaction networks that transform out-of-equilibrium ‘fuel’ to ‘waste’ are the engines that power the biomolecular machinery of the cell. Inspired by such systems, autonomous artificial molecular machinery is being developed that functions by catalysing the decomposition of chemical fuels, ...

Reaction yield is indicated as percent of cyclic peptide acylated with carboxylic acid and was determined by LC–MS. Source data Full size image We next tested the efficiency of the cyclization reaction by combinatorically reacting the eight peptides, P1–P8, with four different bis-electrophilic ...
Designing molecular keys and combining advanced encryption standard cryptography with molecular steganography is a secure way for encoding messages. Here, the authors use the Ugi four-component reaction of perfluorinated acids to create a library of 500,000 molecular keys for encryption and decryption. ...
The reaction between different carboxylic acids and iron was performed by monitoring the amount of iron dissolved in oil through the formation of the iron carboxylate and by the product distribution in the gas phase. It was found that the solubility of the given iron carboxylate strongly influences...
