Procedure-dependent construction of two isomers of trimeric self-assembled boronic esters†
Abstract
A procedure-dependent selective construction of two isomers of trimeric boronic esters was realized. A capsule-like trimeric boronic ester was constructed by the direct connection of two kinds of self-assembled boronic esters via [3+2] cycloaddition, while the tricyclic trimeric boronic ester was obtained by the self-assembly of pre-connected components.
