J. Wuckelt et al., A NEW AND CONVENIENT SYNTHESIS OF ALPHA-TETRAMIC ACID-AMIDES VIA A COBALT(II)-MEDIATED REACTION CASCADE, Tetrahedron letters, 39(10), 1998, pp. 1135-1138
A novel cobalt(II)-mediated domino reaction of carbon nucleophiles wit
h 1a-d has been developed. The resulting cyclization regioselectively
yields functionalized alpha-tetramic acid amides. (C) 1998 Elsevier Sc
