The synthesis and characterisation of α-oxo aldehyde-supported silicas by the sol-gel procedure is described. The glyoxylyl group was generated after gelation, either by periodic oxidation of gluconamide chains or by deprotection of a diisopropylthioacetal-protected derivative. The accessibility and reactivity of the supported α-oxo aldehyde function was investigated in model reactions with hydroxylamine
描述了通过溶胶-凝胶程序合成和表征 α-氧代醛负载的二氧化硅。通过葡糖酰胺链的周期性氧化或通过二异丙基硫代缩醛保护的衍生物的脱保护,在凝胶化后生成乙醛基。在与羟胺和肼衍生物的模型反应中研究了支持的 α-氧代醛功能的可及性和反应性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
