Aminoacyl adenylate pentacoordinated phosphorus compounds were analyzed by field desorption (FD) and fast atom bombardment (FAB) mass spectrometries, together with the B/E linked scan technique, and their mass spectral fragmentation pathways were investigated. For the five bonds (one P–N bond, three P–O bonds and one mixed anhydride bond P–O–CO), the cleavage usually occurred more on the P–N bond, the mixed anhydride bond and the O–C bond adjacent to the P–O bond, and less on the P–O bond. Ion YH + , corresponding to water loss from protonated 2′,3′‐ O ‐isopropylidene‐adenosine, was the base peak. The results reflect the structural characteristics of aminoacyl adenylate pentacoordinated phosphorus compounds. Copyright © 1999 John Wiley & Sons, Ltd.
