Sugars seleno

Synthesis, transformations, and biological properties of nucleosides modified by sulfur and seleno sugars 93T9877. [Pg.335]

Y. Kobayashi, Y. Ogra, K. Ishiwata, H. Takayama, N. Aimi, K. T. Suzuki, Seleno-sugars are key and urinary metabolites for selenium excretion within the required to low-toxic range, Proc. Natl Acad. Sci. USA, 99 (2002), 15932-15936. [Pg.639]

II. Preparations of Seleno Sugar Derivatives 1. Early Work... [Pg.145]

In a number of reports, Zingaro and co-workers35-42 described several transformations in seleno sugars that involved the application of such selenium reagents as selenourea and potassium selenocyanate in this synthesis of diselenides 43, 46, and 49. The first approach involves the SN2 displace-... [Pg.148]

III. Application of Seleno Sugars in Synthesis 1. Utilization of Selenoglycosides in Glycosylation Reaction... [Pg.167]

The synthesis and application of selenium intermediates and seleno sugars, and the subsequent study of their transformation into various classes of useful precursors and target derivatives, are witnessing rapid new development. This new field of synthetic carbohydrate chemistry offers new methodologies for general organic and natural-product syntheses, and new... [Pg.193]

Sedimentation, enzyme molecular-weight determination by, 287 Sedimentation coefiBcients of a-amylases, 309 of /3-amylases, 333 of phosphorylases, 348 Selenium, in hemiacetal rings of monosaccharides, 206 Seleno sugars, 232 Septanoses, 228... [Pg.515]

A number of important reactions of the poly-O-acylglycosyl halides have been reviewed already in Advances in Carbohydrate Chemistry and there is no need to discuss further the formation of glycals and of thio and seleno-sugars or the Grignard processes. ... [Pg.245]
