✦ Synopsis

The synthesis and resolution of two chiral carbocyclic cleft molecules containing carbonyl groups on the periphery of the cavity are reported. These compounds are reminiscent of TrBger's base but contain a smaller cleft and additional carbonyl (or alcohol) groups.

X-ray crystal structures of the dibromo and dimethyl derivatives show that the dihedral angle between the two aromatic rings is 79" and 85" respectively.

Two selectors derived from [(S)-1-(1-naphthyl)ethyl]amine and (S)-leucine have been chemically bonded to one another and the resulting chiral auxiliary linked covalently to silica gel, to produce a new chiral stationary phase (CSP) for the HPLC resolution of enantiomers. The CSP is able to separate
