Influence of the surfactant degree of oligomerization on the formation of cyclodextrin: surfactant inclusion complexes
(Elsevier, 2020)
Supramolecular complexation is an attractive strategy to modulate the performance of surfactants, e.g., by host-guest interactions. Here, we investigate the interaction of single-chained, di-, tri-, and tetrameric cationic ...

Synthesis of Novel 3-Amino(Hydroxy)methyl-l-fuco-Azafagomines as Leads for Selective Inhibitors of α-l-Fucosidases
(2010)
The synthesis of 3-substituted l-fuco-azafagomines from d-lyxose is reported. They represent the first example of aza-C-glycosides having a biimino (-NH-NH-) moiety. The key step of the synthesis is the introduction of the ...
