Salt and iron ease the way to amines Adding nitrogen to carbon compounds is often a laborious process. The nitrogen typically needs protection to prevent undesired reactivity, and the protectinggroups can be hard to remove afterward. Legnani et al. report a versatile method to add unadorned NH2 from a hydroxylamine derivative directly to a double-bonded carbon center. A simple iron catalyst manipulates
A series of substituted N-cycloalkyl benzamides, cinnamamides, and indole-3-carboxamides were synthesized and evaluated for their analgesic, antiinflammatory activities as well as for their gastrointestinal irritation liability. Indomethacin was used as reference drug in both tests. Compounds 1k, 1b, 1h, 1j, and 1g were the most active in the antiinflammatory paw edema inhibition test, with a sharply dose-dependent effect. In terms of the analgesic activity (acetic acid writhing test), the most active compound was 5a followed by 3a, but many other compounds were found to have a non-negligible potency. Even in this case, the effect was dose dependent.
