Abstract
A new type of cyclic steroidal dimer based on brassinosteroids has been synthesized via the reaction of 24-epibrassinolide with 1,4-phenylenediboronic acid and structurally characterized by single-crystal X-ray diffraction and 2D NMR analysis. The crystal structure of the dimer was found to contain rather large solvent accessible voids.
► The reaction of 24-epibrassinolide with 1,4-phenylenediboronic acid has been studied. ► A cyclic dimer product 3 with steroid units joined head-to-tail has been isolated. ► The absolute configuration of 3 has been determined by single-crystal X-ray. ► The total cell volume was filled with disordered solvent.
