The synthesis of some ebselen analogues and diaryl diselenides, which have amino acid functions as an intramolecularly coordinating group (SeO) has been achieved by the DCC coupling procedure. The reaction of 2,2-diselanediylbis(5-tert-butylisophthalic acid) or the activated ester tetrakis(2,5...

Aminoacylases are highly promising enzymes for the green synthesis of acyl-amino acids, potentially replacing the environmentally harmful Schotten-Baumann reaction. Long-chain acyl-amino acids can serve as strong surfactants and emulsifiers, with applica

Given the importance of generating more diverse, mutationally more robust and catalytically more competent biopolymers (enzymes), composed of a high number of different residues (amino acids, up to 20 ‘letter’ digits, vigintits), translated from polymers that are far less performant catalysts (...
The positive influence of the piperazinyl substituent per se was examined via its replacement by a primary amino group. Compounds 50 and 51 were prepared by amide synthesis of the carboxylic acid 2 with the corresponding aniline giving the N-(nitrophenyl)benzamides 52 and 53 which were afterwards...
