• compounds exhibited a larger effect than native β-cyclodextrin, and characteristic differences were noted. These differences in activity were correlated with the structural and electronic parameters of the substituents. In addition, the relatively strong effect of the cyclodextrin derivatives on cyclosarin

• , acetylcholinesterase (AChE). Moreover, the results indicate that the mode of action of these cyclodextrin derivatives involves the formation of an inclusion complex with the OP. The question thus arises as to whether suitable cyclodextrin derivatives could also be used in vivo as antidotes against OP poisonings. Such

In terms of structure, these compounds

• 19% yields, respectively. Finally, the reactions of the cyclodextrin derivatives 2a–2c with 1c afforded the corresponding carboranylcyclodextrins 3ca, 3cb, and 3cc in 18, 19 and 20% isolated yields, respectively. It is also of note to mention here the impressive E-selectivity of the cross-metathesis
