  Chemoenzymatic synthesis of [3,9-13C]-labeled NeuAc and KDN

  摘要：

  The chemoenzymatic synthesis of C-13-labeled sialic acid (NeuAc) and 3-deoxy-D-glycero-D-galacto-2-nonulosonic acid (KDN) as useful molecular probes for studying the conformation of sialyl or KDN oligosaccharides attached to proteins was performed by using [6-C-13]-ManNAc, [6-C-13]-Man and [3-C-13]-pyruvic acid sodium salt. In the synthesis of the compounds, 5,6-anhydro intermediates were found to easily provide not only 6-C-13-labeled but also 5-, and 6-modified NeuAc and KDN analogs. Furthermore, it was demonstrated that identical results are obtained by NMR for both [3 ,9-C-13]-NeuAc and 1:1 mixtures of [3-C-13]- and [9-C-13]-NeuAc. (C) 2003 Elsevier Science Ltd.
