✦ Synopsis

The utility of benzoyl and pentadeuterobenzoyl derivatives of peptide methyl esters for mass spectrometric analysis was investigated. The mass spectra of the glu-his and the Val-tyr-pro derivatives are discussed. Treatment of the peptide methyl esters with the mixed benzoic-ethylcarbonic anhydride did in some cases lead to benzoyl derivatives as well as to ethoxycarbonyl derivatives. * For Part I see Ref. 3.
