Synthesis and X-Ray Crystal Structure of a New 'Cholaphane' with Externally Directed Functionality

The 'cholaphane' 1 was synthesized in 26percent overall yield from cholic acid and its structure determined by X-ray crystallography; the molecule adopts an open conformation and is able to surround two molecules of tetrahydrofurane.
