合成路线图解说明:

The partial acylation of 11beta,17a alpha(dihydroxy-D-homopregna-1,4-diene 3,20-dione (I) with 2,2-dichloroacetyl chloride gives the corresponding compound (II), which is acylated again with butyric anhydride yielding 17a alpha-butyryloxy-11beta-dichloroacetoxy-D-homopregna-1,4-diene-3,20-dione (III). Finally, this compound is hydrolyzed partially with aqueous NH4OH and methanol.
