  Stereoselective synthesis and biological activity of novel spiro-oxazinanone-C-glycosides

  摘要：

  The stereoselective synthesis of novel spiro-oxazinanone nucleosides 9 and 10 has been achieved by microwave assisted 1,3-dipolar cycloaddition of exo-glucal (1) and nitrones (2), and followed by reduction, stereospecific recyclization, and catalytic deprotection. The structures of the spironucleosides were determined according to the H-1 NMR, C-13 NMR, 2D NMR, MS, and X-ray analyses, and the biological activities of the title compounds against glycosidases (alpha-amylase, alpha-glucosidase, and beta-glucosidase) and cytotoxicity were also evaluated.
