A simple procedure was developed for the monoacylation of several unprotected alkanediamines with carboxylic acids by using PyBOP-HOBt as coupling agent in the presence of DIEA at room temperature. Yields were moderate with primary alkanediamines and good to excellent with linear or cyclic secondary ones. To illustrate the utility of these monoacylated products, six unsymmetrical diacylated alkanediamines were synthesized. In addition, one of these compounds was evaluated as organocatalyst in an asymmetric aldol reaction.

Time-resolved/steady-state fluorescence and mass spectrometry measurements have shown the preferential binding of a non-steroidal anti-inflammatory drug (NSAID) like naproxen 4 to a synthetic pseudopeptidic receptor built using Phe (9), i.e., bearing an a
Novel acyclic ligands. 3. The syntheses of some amino amides derived from amino acids
Elsworth, John F.,Msimang, Lorenzo N.,Jackson, Graham E.

The syntheses of variously protected amino amides derived from the reaction of oxalic esters with ethylenediamine and with the amino acids glycine, L-valine, and L-lysine are described in this paper. The products are potential contrast agents in magnetic resonance imaging (MRI).
