- 論文の詳細を見る
α-N-Glycosides of 3-deoxy-D-glycero-D-galacto-2-nonulosonic acid (KDN) having a nucleobase, such as uracil, thymine, 5-fluorouracil or cytosine, were synthesized. Their acetone-sensitized photocycloaddition to 2, 3-dimethyl-2-butene under near-UV irradiation gave a pair of diastereomers having a cyclobutane ring. The absolute configuration of the bridgehead carbon atoms in the products was identified by measurement of specific rotation as well as <SUP>1</SUP>H-NMR spectral analysis.
