In this study a general, efficient and environmentally benign solution phase synthesis of 2,5-diketopiperazines (DKPs) using microwave assisted heating in water is described. A series of 11 structurally different DKPs have been synthesized from dipeptide methyl esters. A range of common laboratory solvents have been tested as well as different reaction times and temperatures. Both classic thermal and
Thioester-mediated peptide bond formation has recently garnered a lot of attention, most notably in its relevance to condensation of large peptide fragments. Herein, a simple and general ligation method for the preparation of linear and cyclicpeptides, starting from peptide thioester, mainly p-chlorophenyl, precursors is reported. The inherent advantages of this method are the low epimerization, reduced
