  • Patent number: 7009063
    Abstract: The present invention relates to a process for the synthesis of oxandrolone from mestanolone. The process comprises the steps of: (a) oxidizing mestanolone to form 17?-hydroxy-17?-methyl-5?-androst-1-en-3-one; (b) hydroxylating the 17?-hydroxy-17?-methyl-5?-androst-1-en-3-one to form 1?, 2?, 17?-trihydroxy-17?-methylandrostan-3-one; (c) cleaving the 1?, 2?, 17?-trihydroxy-17?-methylandrostan-3-one to form 17?-hydroxy-17?-methyl-1-oxo-1,2,-seco-A-nor-5?-androstan-2-oic acid; and (d) reducing the 17?-hydroxy-17?-methyl-1-oxo-1,2,-seco-A-nor-5?-androstan-2-oic acid to form oxandrolone.

  • Patent number: 4990610
    Abstract: Sucralfate is prepared in good yields and in newly useful form first by reacting sucrose with chlorosulfonic acid in 2-picoline. The amonium salt is then formed and reacted with aluminum chlorohydrate in specific sequence and alcoholic solvent. The two distinct products have unexpected pharmaceutical and physical characteristics. The oral liquid suspensions also must be critically formulated.
