Selective steroid recognition by a partially bridged resorcin[4]arene cavitand

Author affiliations

Abstract

The partially bridged resorcin[4]arene cavitand 1 featuring a cleft-shaped recognition site formed by two anti-quinoxaline bridges and four convergent HO-groups was prepared in three steps and characterised by X-ray crystallography; cavitand 1 was found to be a selective receptor for steroidal substrates in CDCl3, with the best binding observed for steroids with a flat A-ring and two H-bonding sites on rings A and C/D.
