Description
A trademark of Merck KGaA, Darmstadt, Germany PyBOP is a well-established, effective coupling reagent. It has been developed to replace BOP which generates the carcinogenic HMPT as a by-product during coupling. Contrary to activation with uronium/aminium-type coupling reagents, by-products resulting from guanidinylation of the amino group cannot be formed. PyBOP has been used as well for obtaining peptide thioesters.
