Conclusions
-
1.
The reduction ofβ-triketones of the 2-acetyl-1,3-cyclohexanedione series, and also their 1(3)-O-methyl esters, with zinc in the presence of a proton donor leads to the predominant removal of the C=O function in the side acetyl group.
-
2.
In contrast to the 3-amino-2-acetyl-2-cyclohexen-1-ones, the corresponding 3-N-acetamido derivatives are easily converted under the indicated conditions toβ-diketoamides, which are devoid of the C=C bond.
