It is to be explained how the results of specific reactions carried out on D-glucose and D-mannose agree with the currently known structures of the two sugars. The type of sugar that was produced when D-glucose was reacted should also be determined. Concept introduction: A chiral compound contains at least one carbon which is bonded to four different atoms or groups. D-sugar is one in which the OH group, attached to the highest numbered chirality center, is present on the right side of the vertical chain in Fischer projection. During a rotation of 180 0 in the plane of paper for the Fischer projection, the groups which are on the right side switch places with the groups which are on the left side.

4. An iterative approach to oligosaccharide synthesis involves the use of protected glycals (sugars with C1-C2 double bond) as shown below. The product from the reaction of the first glycal with DMDO under anhydrous conditions is treated with another suitably-protected glycal to form a disaccharide glycal, and the process can be repeated to form a trisaccharide glycal, and so on... Crucial to the success of this approach is the stereoselective formation of the intermediate A in the scheme below. Draw the structure of A. DMDO CH₂Cl2 A OH ZnCl₂, THF OH
