Abstract
A comparative study of reaction conditions was performed for the synthesis of a 2- O-monobenzyl ether of cyclomaltoheptaose (β-CD). Optimal conditions involved sodium ethoxide in Me 2SO and benzyl bromide. The methodology was extended to the preparation of various 2 I- O-iodobenzyl and 2 I- O-carboxymethylbenzyl derivatives of β-CD including a 3-carboxymethyl-4-iodobenzyl derivative of interest as precursor of an enzyme mimic to degrade the organophosphoryl ester diethyl 4-nitrophenyl phosphate (paraoxon).
