Abstract:

A novel and facile silver-catalyzed [5+1] annulation reaction between 2-vinylanilines with benzisoxazoles was developed, resulting in the rapid formation of structurally diversified 2-quinolinylaniline derivatives containing NN-bidentate chelating skeleton in moderate to excellent yields. This protocol features broad substrate scope, high atom-economy, mild reaction conditions and so forth, which provides a new idea for the synthesis of NN-bidentate chelating molecules widely used.

Key words: 2-Vinylaniline, Benzisoxazole, [5+1] Cyclization, 2-Quinolinylaniline, N, N-Bidentate chelating molecule
