Abstract

Glycoluril derivatives bearing free ureidyl groups (1) and bis (cyclic ethers)(2) are the fundamental building blocks for the synthesis of cucurbituril, its derivatives, and its congeners. The known derivatives of 1 and 2 fall into two main classes—those bearing alkyl or aryl functional groups on their convex face. In this paper we present a third class of glycolurils, namely those bearing substituents that are electron withdrawing in character. ...
