[structure: see text]. A new strategy for the synthesis of substitutedazulenes is reported, based on the reaction of beta'-bromo-alpha-diazo ketones with rhodium carboxylates. The key transformation involves intramolecular addition of a rhodium carbenoid to an arene pi-bond, electrocyclic ring opening, beta-elimination, tautomerization, and trapping to produce 1-hydroxyazulene derivatives. The synthetic

A method is provided for protecting against and/or treating ulcerative gastrointestinal conditions, including anti-inflammatory drug-induced gastrointestinal ulcers, using a thromboxane A₂ receptor antagonist. In addition, a combination is provided which includes a thromboxane A₂ receptor antagonist and an anti-inflammatory agent which combination may be used to treat inflammatory conditions, such as arthritis, while inhibiting formation of and/or treating gastrointestinal ulcers.
