General description

Peptide coupling reagent which suppresses enantiomerization [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]. Reduction of carboxylic acids activated with BOP provides a facile route to alcohols [16]. Novabiochem® recommends the replacement of BOP by PyBOP (for PyBOP please see 851009). The manufacture of BOP, as well as its utilization, involves the use or the formation of hexamethylphosphotriamide, the carcinogenicity and respiratory toxicity of which has been the subject of numerous reports.
