Process and intermediates for optically active 3-formyltetrahydropyrans
This invention relates to certain benzoxazolinones which inhibit lipoxygenase and/or cyclooxygenase enzymes. Such compounds are useful in inhibiting such enzymes, per se, and are useful in treating allergic and inflammatory conditions in a mammal. This invention also relates to methods of inhibiting lipoxygenase and/or cyclooxygenase in a mammal with such benzoxazolinones; methods of treating an allergic condition in a mammal with such compounds; methods of treating an inflammatory condition in a mammal with such compounds; and pharmaceutical compositions comprising the benzoxazolinones hereof.
