摘要
Methyl and ethyl esters of valine and leucine were reacted with ferrocenecarbaldehyde to obtain azomethines (C5H5)Fe(C5H4CH=NCHRCOOR′) whose reactions with sodium borohydride provide ferrocenylmethyl derivatives (C5H5)Fe(C5H4CH2NHCHR⋅COOR′) [R=(CH3)2CH, (CH3)2CHCH2; R′ = CH3, C2H5]. The latter compounds react with sodium hydroxide to give, after treatment of the reaction mixtures with acetic acid, N-substituted amino acids (C5H5)Fe(C5H4CH2NHCHRCOOH).
