Post‐source decay (PSD) matrix‐assisted laser desorption/ionization time‐of‐flight mass spectra were found to be useful for the structural elucidation of a series of tris[2‐(glycosylthiourylene)ethyl]amines. The reported fragmentation behaviours of [M+H] + , [M+Na] + and [M‐H] ‐ ions differ from each other significantly; however, they can be compared to tree pruning in every case. Whereas detailed structural information on unprotected glycoclusters is obtained from all PSD experiments, only the positive‐ion mode can be used to gain relevant information about the acetylated glycoclusters. © 1998 John Wiley & Sons, Ltd.
