Abstract
We report on the synthesis of the alkylidene alpha-thiotetronic acids 11 and 12a and a variety of their derivatives, starting with 2,3-dimet hoxysuccinic thioanhydride (4) or diethyl 3-thioxoglutarate. The rhodi um(II) -catalysed decomposition of the diazoketone 26 furnishes the re ductone 12p and the aminoreductone 12r with the thietanone 27 as one o f the by-products.
