Solution-phase reductive cyclization of 2-quinoxalinol analogs: systematic study of parallel synthesis

Mol Divers. 2004;8(2):165-74. doi: 10.1023/b:modi.0000025639.89179.60.

Abstract

1,5-Difluoro-2,4-dinitrobenzene starting material was treated via primary and/or secondary substitution with a variety of amino acids or amines and the aromatic m-dinitro groups were then reductively cyclized provide the 2-quinoxalinol analogs. The conditions for 1,5-dialkylamino-2,4-dinitrobenzene reduction have been systematically studied and optimized in solution. Three effective methods are described for the high-throughout generation of 2-quinoxalinol analogs.
