title: Partial synthesis of 23-hydroxyursolic acid isolated from medicinal plants of the Rubiaceae family.
abstract: 23-Hydroxyursolic acid (2), previously isolated from medicinal plants of the Rubiaceae family, was synthesized in ten steps via methyl 23-hydroxy-3-oxours-12-en-28-oate (5) from commercially available ursolic acid (6).
