Acylation of oxazoles by the copper-mediated reaction of oxazol-2-ylzinc chloride derivatives

Abstract C-2 acylation of oxazole derivatives is accomplished by reaction of oxazol-2-ylzinc chloride reagents with acid chlorides in the presence of cuprous iodide. O-acylated vinylisonitriles, which are the sole product from the corresponding reaction employing lithiooxazole, are not observed. The method accommodates substituted and unsubstituted oxazoles with a variety of acid chlorides.

Synthesis and anticonvulsant activity of 3-aryl-5H-2,3-benzodiazepine ampa antagonists

A novel series of 3-aryl-5H-2,3-benzodiazepines with N-3 aromatic substituents has been synthesized. Good in vivo anticonvulsant activity of the new compounds has been demonstrated employing the maximal electroshock seizure test in mice. Evaluation of a subset of the compounds in the cortical wedge assay confirmed the new structures to be AMPA antagonists.
