Synthesis of soluble combinatorial libraries of crown ether-ester analogues via the cyclodepolymerisation of linear polyesters

Abstract

Cyclodepolymerisation of functional linear polyesters gives macrocycles which, on equilibration via transesterification, give soluble combinatorial libraries of crown ether-ester analogues, one consisting of 30 different 18- or 27-membered rings and another consisting of 29 different 24- or 36-membered rings.
