Selective Modification of β-Cyclodextrin on the Secondary Side 4:Preparation of Arylated β-Cyclodextrins with a Flexible Chain

摘要

Mono 3 -deoxy-(N’ -benzoyl-ethylenediamino)-β -CD, mono 3 -deoxy-(N’ -benzimidoyl -ethylamino)-β-CD, and mono 3 -deoxy-(N’ - salicylidene-ethylenediamino)- β -CD, each of which has a flexible chain that bonds the aryl moiety on the secondary side of β-CD, were prepared inthis research. The reaction processes might involve the formation of mono(2, 3 -manno-epoxide )- β -CD as an intermediate in our reaction conditions.
