A convenient procedure has been developed for the synthesis of 3β,28-diacetoxylup-20(29)-en-30-oic acid via oxidation of 3β,28-di-O-acetylbetulin with selenium dioxide in aqueous ethanol on heating, followed by oxidation of 3β,28-diacetoxylup-20(2

3β,28-Diacetoxylup-20(29)-en-30-oic acid (obtained via oxidation of betulin diacetate) enters the addition reaction with P—H-phosphonium salts (triarylphosphonium trifluoroacetates) under mild conditions to afford β-carboxyalkylphosphonium salts.
