trans-Pyridylcinnamide has been established as an alternative hydrogen bonding synthon, in place of urea for carboxylate binding. This alternative motif has been used in the design and synthesis of new fluorescent 'On-Off' signalling chemical sensor 1, which is found to bind aliphatic dicarboxylates with moderate binding constants. The recognition ability has been established by fluorescence, UV-vis and 1H NMR spectroscopic methods. The receptor is found to be selective for long chain pimelate.

A novel and facile boric acid catalyzed direct amidation between amino-azaarene compounds and carboxylic acids has been developed. The amidation proceeded cleanly and provided good to excellent yields of the desired amides. Boric acid is a green and inexpensive catalyst. We have also found that N,N,N′,N′-tetramethylpropane-1,3-diamine acted as an additive accelerating this boric acid catalyzed amidation. A mixed acid anhydride is postulated to be the active intermediate responsible for this successful amidation. This direct amidation is an atom- and step-economical reaction.
