CUCURBITNURILS AND METHOD FOR PRODUCING SAID CUCURBITNURILS

摘要

A method for producing cucurbit[n]urils, where n is from 4 to 12, comprising mixing substituted and/or unsubstituted glycoluril with an acid and a compound that can form methylene bridges between glycoluril units, and heating the mixture to a temperature of from 20° to 120° to thereby form cucurbit[n]. Novel cucurbit[n]urils, where n = 4, 5,7, 8, 9, 10, 11 and 12 and substituted cucurbit[s,u]urils, where s = number of substituted glycoluril units, u = number of unsubstituted units and s + u = 4 - 12 are also described.
