合成路线:This compound can be obtained by two different ways:1) The oxidation of 21-desoxyprednisolone (I) with chromium trioxide and manganous nitrate in acetic acid gives 21-desoxyprednisone (II),which is esterified with propionic anhydride and p-toluenesulfonic acid yielding 21-desoxy-17-O-propionylprednisone (III).Finally,this compound is reduced with KBH4 in DMF - water.2) The esterification of 21-O-(methanesulfonyl)prednisolone (IV) with acetyl nitrate in acetic acid gives 21-O-(methanesulfonyl)-11-O-nitroprednisolone (V),which is treated with NaI and NaHSO3 in acetic acid yielding the corresponding 21-desoxy nitrate ester (VI).The esterification of (VI) with propionic anhydride as before affords 21-desoxy-11-O-nitro-17-O-propionylprednisolone (VII),which is finally denitrated with Zn powder in acetic acid.
