The present invention is directed to compounds that are antagonists of CGRP receptors and that are useful in the treatment or prevention of diseases in which the CGRP is involved, such as headache, migraine and cluster headache. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which CGRP is involved.

Herein, we report Fe(III)(TPP)Cl as an effective catalyst for promoting arene C–H amidation throughintramolecular cyclization of N-tosyloxyarylcarbamate substrates. The reaction proceeds via nitrene (outer sphere pathway) C(sp2)–H insertion to yield benzoxazolones under external-oxidant-free conditions at ambient temperature. The method is operationally simple and scalable with high-functional-group

Certain 6-aryl- or 6-heteroaryl- alkylaminobenzoxazolones, and their pharmaceutically-acceptable salts, are dual inhibitors of lipoxygenase and cyclooxygenase enzymes, and so are useful as antiallergy and antiinflammatory agents.
