Abstract
Diferrocenyl acidamide 8 was synthesized through six steps starting from L-valine and ferrocene.First L-valinol was obtained by reduction of L-valine using NaBH4 as reducing agent.On the other hand,ferrocenyl acid 3 was synthesized and then transferred into acyl chloride.The later was directly reacted with L-valinol to afford compound 6 in the condition of Et3N.Compound 8 was finally obtained by transformation of compound 6 into the chloride 7 which needs not be separated coud dcrectly reacted with p-CH3PhSO2NHNa.IR and NMR spectra were used to confirm the structure.
