derivative 3a (monoclinic space group P2(1), a = 10.301(1) A, b = 9.647(1) A, c = 18.479(2) A, beta = 102.98(2) degrees, Z = 4). Further peptide chemistry at the C terminus proceeds smoothly as demonstrated by the synthesis of the ferrocene labeled dipeptide Fc-CH2-Phe-Gly-OCH3 5 (Fc = ferrocenyl ((eta-C5H4)Fe(eta-C5H5))). We also report the synthesis of the C,N-bis-ferrocene labeled tripeptide Phe-Ala-Leu
为了识别除最简单的天然分子以外的所有分子,基于二茂铁的电化学传感器肯定需要手性中心。为了推进必要的化学反应,这项工作描述了对映体纯氨基酸,肽和其他手性胺的二茂铁衍生物的合成和性质。二茂铁醛与氨基酸酯缩合,生成相应的席夫碱2,在甲醇中被NaBH4还原为二茂铁甲基氨基酸3。对苯丙氨酸衍生物3a(单斜晶系空间)进行X射线单晶分析组P2(1),a = 10.301(1)A,b = 9.647(1)A,c = 18.479(2)A,beta = 102.98(2)度,Z = 4)。二茂铁标记的二肽Fc-CH2-Phe-Gly-OCH3 5(Fc =二茂铁基((eta-C5H4)Fe(eta-C5H5)))的合成证明,C末端的进一步肽化学反应进展顺利。我们还报告了C,N-双二茂铁标记的三肽Phe-Ala-Leu的合成及其电化学表征。从由二茂铁醛和L-1-氨基-乙基苯合成的对映体纯的二茂铁衍生物9开始,
