The derivative of glycyrrhetinic acid which have similar effects of desoxycorticosterone acetate was prepared glycyrrhetinyl chloride by the chlorination with thionyl chloride at low temperature. 2-Acetyl-11-keto-.DELTA. : 13 oleanolic ketol acetate (30) was synthesized by diazotating glycyrrhetinyl chloride with diazomethan and the acetylation with anhydro acetic acid. 2-Acetyl-.DELTA.12 : 13 oleanolic ketol acetate (28) was synthesized by chlorinating oleanolic acid with thionyl chloride, and by diazotatating oleanolyl chloride with diazomethan and the acetylation with anhydroacetic acid.
