Glucose with germanic acid

A comparative study of the chelation of 2-deoxy-D-ribose with boric, germanic, telluric, and arsenious acids using potentiometry has shown that only 1 1 complexes are formed. Values of the chelation constants were compared with those of the pentoses. A similar study on mannitol and glucose with boric acid demonstrated that the former was about 740 times more effective a complexant than glucose, but that the conclusions were complicated by the degree of association of boric acid in solution. Reactions at the anomeric centre of mannofuranose have been carried out by means of the 2,3 5,6-ethylboronate (1) formed by treatment of D-mannose with limited triethyl boroxine. By the same means D-lyxose gave the 2,3-blocked lyxofuranose (2) also useful for... [Pg.138]
