5.Which of the following open-chain forms would lead to the cyclic pyranose shown below?
The label has fallen off a bottle that contains a sugar with the formula C6H12O6. Oxidation of the unknown sugar at both ends gives an optically active dicarboxylic acid, A. The β-pyranose of the unknown sugar is found to contain two axial substituents. Select the structure that represents the original sugar in the bottle.
An aldohexose, A, is reacted with Br2/H2O to yield an aldonic acid, B. The other end of B is oxidized to yield an optically active sugar, C. Reaction of C with one equivalent of LiAlH4 in Et2O followed by workup with H2O results in only one unique product, D. Of the eight naturally occurring D-aldohexoses, how many can satisfy the conditions of this problem?
