An nBu4NI-catalyzed oxidative cross-dehydrogenative-coupling of β-dicarbonyl compounds with acetone under mild reaction conditions is described. This methodology provides a straightforward pathway to synthesize 2-carbonyl-1,4-diketones and feat
N-Heterocyclic carbene-catalyzed double acylation of enones with benzils
Takaki, Ken,Ohno, Akira,Hino, Makoto,Shitaoka, Takashi,Komeyama, Kimihiro,Yoshida, Hiroto
, p. 12285 - 12288 (2014/12/11)
Thiazolium carbene-catalyzed reaction of aromatic 1,2-diketones with enones in aprotic solvents gave double acylation products in good yields, whereas hydroacylation products formed by Stetter reaction were not detected at all. These results suggested the generation of aroyloxyenamine species from the 1,2-diketones instead of hydroxyenamines (Breslow intermediates). This journal is
EINE NICHT ERWARTETE UMLAGERUNGSREAKTION VON VERZWEIGTEN TRIKETONEN
Stetter, Hermann,Jonas, Friedrich
, p. 4945 - 4948 (2007/10/02)
Heating 2-acyl-alkane-1,4-diones 1 to temperatures above 120 deg C causes an acylgroupmigration leading to 3-acyl-alkane-1,4-diones.
