Additional flexibility solves the leaving group problem in cyclodextrin acylation
Breslow, Ronald,Chung, Shin
, p. 631 - 634 (1990)
The rate of acylation of β-cyclodextrin by substituted phenyl esters of adamantanepropiolic acid shows a normal dependance on the basicity of the leaving group. This shows that the abnormal behavior in acylation by ferroceneacrylate esters can be solved w
