Propane-1,2,3-tricarboxylic acid was also used as template for the preparation of artificial siderophores 22 and 23. A structurally similar template, bis(carboxymethylamino) acetic acid, was used to prepare 24. AU three showed identical growth promotion of several strains of E. coli. ... 

The resulting tetraethyl ester on hydrolysis and decarboxylation yields propane-1, 2,3-tricarboxylic acid.155 In this example the malonate anion is generated by using one molar proportion of sodium ethoxide this is Michael s original method. However, these conditions sometimes lead to competing side reactions and the formation of abnormal reaction products. Better yields of the required product are often obtained with small amounts of sodium ethoxide (the so-called catalytic method) or in the presence of a secondary amine (e.g. diethyl-amine, see below). 

Fumonisins are a group of toxins produced primarily by Fusarium verticil-lioides (formerly called F moniliforme), Eprolifemtum and other related species which readily colonize corn all over the world [120-124]. Nine structurally related fumonisins including Bj, B2, B3, B4, A, and A2, have been described (fig. 8). Chemically, fiimonisin Bj is a derivative (diester) of propane-1,2,3-tricarboxylic acid of 2-amino-12,16-dimethyl-3,5,10,14,15-pentahydroxy-icosane [121-130]. The other fumonisins lack the tricarballylic acid or other ester groups [121, 131, 132]. Fumonisins are chemically similar in structure to toxins (AAL) produced by Altemaria altemata [133]. Production of fumonisins hy Altermria has also been reported [134,135], and some fumonisin-producing Fusaria have been knovm to produce AAL toxins [136].
