Complete structures of the sphingosine analog mycotoxins fumonisin B1 and AAL toxin T(A): Absolute configuration of the side chains

Article abstract of DOI:10.1016/0040-4039(95)00090-Y

Fumonisin B₁ and AAL toxin T(A) are sphingosine-analog mycotoxins characterized by propane-1,2,3-tricarboxylic acid side chains esterified to alkylamine backbones. The absolute configuration of all stereogenic centers in the backbones is known. Using chiral gas chromatography methodology we have determined the absolute configuration at C-3' in the side chains to the S, thereby completing structure determination of both toxins.
