    Abstract: The present invention provides a class of substituted indene compounds and their pharmaceutically acceptable salts which possess selective estrogen receptor modulator (SERM) activity and are thus useful in the treatment of osteoporosis and cardiovascular disease, particularly hyperlipidemia in women. The compounds possess the structure ##STR1## in which R.sup.1 is hydrogen, hydroxy, alkoxy, phenylcarbonyloxy, alkylcarbonyloxy, or alkylsulfonyloxy. R.sup.2 is hydrogen, hydroxy, halo, alkoxy, phenylcarbonyloxy, alkylcarbonyloxy, or alkylsulfonyloxy. R.sup.3 is 1-piperidinyl, 1-pyrrolidinyl, methyl-1-pyrrolidinyl, dimethyl-1-pyrrolidinyl, 4-morpholino, dimethylamino, diethylamino, diisopropylamino, or 1-hexa-methyleneimino, and n is 2 or 3. The dashed line bond between the carbon atoms at positions 1 and 2 of the indene nucleus represent an optional double bond with the proviso that when the double bond is absent, the parenthetic hydroxy group at position 1 is present and vice versa.

  • Patent number: 5936124
    Abstract: A synthesis of fluoxetine is disclosed. The process begins with a lower alkyl ester of 3-benzoylpropionic acid, which is reduced in the presence of a chiral ligand to produce the corresponding .gamma.-hydroxy ester, and the ester is cleaved. The free acid is then condensed with the alcohol to form a .gamma.-lactone, which is treated with ammonia to provide the .gamma.-hydroxy amide. The amide undergoes a Hoffman rearrangement to provide a 2-oxo-1,3 oxazine, which is reduced to 3-(methylamino)-1-phenyl-1-propanol. The alcohol is deprotonated and reacted with a 4-chloro- or 4-fluoro benzotrifluoride to provide fluoxetine free base.

  • Patent number: 5892117
    Abstract: Oxidation of secondary amines with hydrogen peroxide and sodium tungstate is reported to give good yields of nitrones. However, when using dimethylamine in this manner, a considerable amount of N,N-dimethylformamide was produced as a co-product. To more selectively produce N-methylnitrone from dimethylamine, a two-step process is used which comprises (a) mixing together dimethylamine and a peroxidic compound, and subjecting the resultant mixture to reaction conditions effective to form a reaction mixture in which N,N-dimethylhydroxylamine has been formed; and (b) mixing together (i) reaction mixture from (a), (ii) a peroxidic compound, and (iii) a transition metal-containing oxidation catalyst, and subjecting the resultant mixture to reaction conditions effective to form a reaction mixture in which N-methylnitrone has been formed. Highest yields of N-methylnitrone are achieved by conducting step (b) at a pH in the range of 7 to about 12, and at a temperature in the range of about -10.degree. to about 100.

  • Patent number: 5276192
    Abstract: A process for preparing phenoxyethanamines from phenols and 2-oxazolines in quantitative yields was discovered. Phosphoric acid hydrolyzes the amide intermediate from the phenol/2-oxazoline reaction without cleaving the amide at the ether linkage and without undesired aromatic ring substitution. Thus, yield to the desired phenoxyethanamines is often 98% or better, requiring no subsequent purification. In contrast, sulfuric and hydrochloric acids give these undesired side reactions. Phenoxyethanamines are useful in thermosetting resins, pharmaceuticals and as surfactants.
