A mild, efficient, and eco-friendly method for the synthesis of o-nitroarylamine from o-nitroaryl sulfonic acid via ipso nucleophilic aryl substitution by amine is described. The products have been obtained with good yields at room temperature without the assistance of any metal, activating agent, or toxic oxidant. This method is useful for racemization-free synthesis of N-aryl amino acid esters.

Nucleophilic aromatic substitution of a 2,4-dinitrophenyl substituted pyrazole 1 with primary amines leads to substitution of the pyrazolo substituent. In these nucleophilic aromatic substitution reactions (S NAr), 5-amino-1H-4- pyrazolecarbonitrile (3) acts as a new leaving group.
Pyrrolylquinoxalinediones: A new class of AMPA receptor antagonists

Pyrrolylquinoxalinediones were synthesized and their affinities for the AMPA receptor were determined. Most compounds showed moderate to good affinities. The acetic acid derivative 8b exhibited a K(i) value of 70 nM and was equipotent to NBQX 1. Structure activity relationships are discussed. Selected compounds were tested for their potency to inhibit AMPA induced lethal convulsions in mice. In this in vivo model the compounds showed improved potency compared with NBQX.
