A concise synthesis of thiophosphate, phenylthiophosphonate, and diphenylthiophosphinate esters bearing a 28a-homolupane residue is reported. The new triterpenes were obtained from the readily available 3-O-acetylichopanol by a nucleophilic substitution of the corresponding mesylate with thiocyanate ion followed by a Michaelis-Arbuzov reaction. These results open the way to new lupane-type derivatives having a thiophosphorus moiety at the lupane core as potential anticancer compounds. Additionally, the cytotoxic activities of the new homolupane compounds were evaluated in vitro.
