SOLVED:(a) Outline a Kiliani-Fischer synthesis of epimeric aldopentoses starting with D-(-)-erythrose (use Fischer projections). (b) The two epimeric aldopentoses that one obtains are D-(-) -arabinose and D-(-) -ribose. Nitric acid oxidation of D-(-) -ribose yields an optically inactive aldaric acid, whereas similar oxidation of D-(-) -arabinose yields an optically active product. On the basis of this information alone, which Fischer projection represents D-(-) -arabinose and which represents D-

SOLVED:What monosaccharides would be formed in a Kiliani-Fischer synthesis starting with one of these? a. D-xylose b. L-threose

The Kiliani-Fischer chain extension is a method for lengthening an aldose chain by one carbon, giving two new aldoses that differ in stereochemistry at C2. D-Erythrose, for instance, yields a mixture of D-ribose and D-arabinose on Kiliani-Fischer chain extension. D-Erythrose D-Pibose D-Arabinose (a) What product(s) would you expect from Kiliani-Fischer reaction of D-ribose? (b) What aldopentose would give a mixture of L-gulose and L -idose on Kiliani-Fischer chain extension? | Numera
