    Abstract: Enantiomerically enriched hydroxychromanones are obtained by the AlCl3-catalyzed intramolecular Friedel-Crafts acylation of the corresponding 3-phenoxy-2-alkylcarbonyloxy-propionic acid followed by cleavage of the carboxylate in the presence of an alkali metal peroxide or hydroperoxide. Enantiomerically enriched cis-aminochromanols can then be prepared by treating the hydroxychromanones with a hydroxylamine and hydrogenating the resulting oxime. The cis-aminochromanols can be employed as intermediates in the production of HIV protease inhibitors which are useful for treating HIV infection and AIDS.

  • Patent number: 5939452
    Abstract: The invention relates to novel benzopyran and other benzo-fused leukotriene B.sub.4 (LTB.sub.4) antagonists of formula I and the pharmaceutically acceptable salts thereof, to pharmaceutical compositions containing such compounds, and to a method of using such compounds as LBT.sub.4 antagonists. The compounds of the invention inhibit the action of LTB.sub.4 and are therefore useful in the treatment of LTB.sub.4 induced illnesses such as inflammatory disorders including rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, psoriasis and other skin disorders such as eczema, erythema, pruitus and acne, stroke and other forms of reperfusion injury, graft rejection, autoimmune diseases, asthma and other conditions where marked neutrophil infiltration occurs.
