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.
提出了由d或1-丙氨酸短而有效地合成两种8-氨基-7-氧代壬酸对映体的方法。该第一化学合成的关键步骤是β-酮膦酸酯3和4-甲酰基丁酸酯苄基的非消旋霍纳-沃兹沃思-埃蒙斯反应。测试了对映异构体对酿酒酵母的促进生长的作用。
