Certain carbocyclic aryl- and heterocyclic aryl- substituted cyclopropyl N-hydroxyureas, N-hydroxy-carboxamides, and N-acyl-N-hydroxyamines inhibit 5- and/or 12-lipoxygenase and are useful in the treatment of inflammatory disease states.

Cyclopropanation of α,β-unsaturated N-methoxy-N-methyl amides provided the cyclopropyl amides in far superior yields to those obtained with the corresponding ketones. The desired ketones are then readily accessible by the addition of organometallicreagents. Access to a variety functional groups, including aldehydes and carboxylic acids, is also described.
