Abstract
A short and efficient synthesis of both 8-amino-7-oxopelargonic acid enantiomers from d or l- alanine is presented. The key step of this first chemical synthesis is the non-racemizing Horner-Wadsworth-Emmons reaction of a β-ketophosphonate 3 and benzyl 4- formylbutanoate. The growth-promoting effect of the enantiomers was tested on Saccharomyces cerevisiae.
