Draw the Haworth projection for the cyclic structure of D-mannose by laying down the Fischer projection.

Short Answer

Expert verified

The Haworth projection for the cyclic structure of D-mannose is drawn below.

Haworth Projection

Step by step solution

01

Fisher Projection

Fischer projection depicts the three-dimensional structure of a molecule on a page, with horizontal lines representing bonds that extend above the plane of the paper, and vertical lines representing bonds that extend away from the viewer.

Haworth Projection of D-mannose

In carbohydrates, closed cyclic structure of molecules is represented by Haworth projection. The distinction between the Fischer and Haworth projections is that the Fischer projection depicts the open chain structure whereas the Haworth projection depicts the closed cyclic structure.

Draw the structures of the compounds named in Problem 23-20 parts (a), (c), and (d). Allose is the C3 epimer of glucose and ribose is the C2 epimer of arabinose.

Cellulose is converted to cellulose acetateby treatment with acetic anhydride and pyridine. Cellulose acetate is soluble in common organic solvents, and it is easily dissolved and spun into fibers. Show the structure of cellulose acetate.

H. G. Khorana won the Nobel Prize in Medicine in 1968 for developing the synthesis of DNA and RNA and for helping to unravel the genetic code. Part of the chemistry he developed was the use of selective protecting groups for the 5鈥� OH group of nucleosides.

The trityl ether derivative of just the 5鈥� OH group is obtained by reaction of the nucleoside with trityl chloride, MMT chloride, or DMT chloride and a base like Et3N. The trityl ether derivative can be removed in dilute aqueous acid. DMT derivatives hydrolyze fastest, followed by MMT derivatives, and trityl derivatives slowest.

(a) Draw the product with the trityl derivative on the 5鈥� oxygen.

(b) Explain why the trityl derivative is selective for the 5鈥� OH group. Why doesn鈥檛 it react at 2鈥� or 3鈥�? (c) Why is the DMT group easiest to remove under dilute acid conditions? Why does the solution instantly turn orange when acid is added to a DMT derivative?

Trehalose is a nonreducing disaccharide (C12H22O11) isolated from the poisonous mushroom Amanita muscaria. Treatment with an 伪 -glucosidase converts trehalose to two molecules of glucose, but no reaction occurs when trehalose is treated with a 尾 -glucosidase. When trehalose is methylated by dimethyl sulfate in mild base and then hydrolyzed, the only product is 2,3,4,6-tetra-O-methylglucose. Propose a complete structure and systematic name for trehalose.
