Design and synthesis of novel chiral dendritic species derived from bile acids

Bile acids have been used for the first time as the building block for the construction of dendritic units. Orthogonally functionalized 7-deoxycholic and cholic acid derivatives were synthesized. The construction of a bile acid heptamer, a nonamer, and a decamer using the convergent strategy are described in detail. Chromatographic, spectral, and optical properties of these molecules have been investigated. Molecular modeling suggests that these molecules have globular shapes with nanometric dimensions.
