Henri Brunner, Bernd Haßler

Open publisher page 6 citations

Abstract

New optically active 3,5-dinitrosalicyloxazolines, derived from 3,5-dinitrosalicylonitrile and the chiral aminodiols (1S,2S)-(+)-2-amino-1-phenyl- 1,3-propanediol, (2S)-(-)-2-amino-1,1,4,4-tetraphenyl- 1,4-butanediol and (2S)-(-)-2-aminol, 1-diphenyl-1,3-butanediol, were prepared and used as in situ catalysts for enantioselective cyclopropanation reactions.
