title: Remarkable structures of cyclotri(deoxycholate) and cyclotetra(24-norcholate) acetate esters.
abstract: X-ray crystallographic determinations and AM1 calculations have defined the solid-state and gas-phase structures of cyclotri(deoxycholate) and cyclotetra(24-norcholate). The latter cyclotetramer is one of the largest open macrocycles ever subjected to crystallography.
