Direct Boronic Acid Promoted Amidation of Carboxylic Acids with Poorly Nucleophilic Amines

open access: yes, 2022
Direct amidation of carboxylic acids with poorly nucleophilic amines such as anilines is a notorious challenge in organic chemistry. Previously reported methodologies for direct amidation tend to report none or just a few examples with simple anilines ...

Interdependent Dynamic Nitroaldol and Boronic Ester Reactions for Complex Dynamers of Different Topologies [PDF]

open access: yes, 2021
Complex dynamic systems displaying interdependency between nitroaldol and boronic ester reactions have been demonstrated. Nitroalkane-1,3-diols, generated by the nitroaldol reaction, were susceptible to ester formation with different boronic acids in ...

Boronic Acid-Based Electrochemical Sensors for Detection of Biomolecules

open access: yesInternational Journal of Electrochemical Science, 2013
Boronic acids can form reversible covalent bonds with 1, 2- or 1, 3-diols to generate five or six-membered cyclic complexes. Thus, boronic acid functionalized compounds and materials have attracted much attention in both chemistry and biology as the ...
