Heating D-altrose with dilute acid produces a nonreducing anhydro sugar (C6H1005). Methylation of the anhydro sugar followed by acid hydrolysis yields 2,3,4-tri-O-methyl-D-altrose. The formation of the anhydro sugar takes place through a chair conformation of ẞ- D-altropyranose in which the -CH2OH group is axial. What is the structure of the anhydro sugar? CH3 OH HO OH I H₂C CH3 0. 0 H H H H HO OH OH I CH3 H₂C H H H H CH₂ -OH OH HO eTextbook and Media Explain how is it formed. The anhydro sugar is formed when the axial -CH2OH group reacts with C to form a cyclic SUPF Because the anhydro sugar is (i.e., an internal glycoside), it is a sugar. Methylation followed by acid hydrolysis converts the anhydro sugar to 2,3,4-tri-O-methyl-D-altrose.

Is sildenafil chiral? If so, which of the possible stereoisomers are formed in this synthesis?
rank the products in the indicated CH2 groups in order of increasing acidity and give reasons why.
Ribose, a carbohydrate with the formula shown, forms a cyclic hemiacetal, which, in principle, could contain either a four-membered, five-membered, or six-membered ring. When D-ribose is treated with methanol in the presence of an acid catalyst, two cyclic acetals, A and B, are formed, both with molecular formula C,H,0, These are separated, and each is treated with sodium periodate (Section 10.8C) followed by dilute aqueous acid. Both A and B yield the same three products in the same ratios. он о CHO СНО H+ CH,OH A +B ÕH 1. NalO, 2.

Two sugars differing in configuration at a single asymmetric carbon atom are known as epimers. D-mannose is a C-2 epimer of glucose (Structure I), while D-galactose is a C-4 epimer of glucose. Structure II and III are II: galactose, III: mannose II: mannose; III: galactose II and III are mannose II and III are galactose
When oxaloacetic acid and acetyl-coenzyme A (acetyl-CoA) labeled with radioactive carbon-14 in position 2 are incubated with citrate synthase, an enzyme of the tricarboxylic acid cycle, only the following enantiomer of [2-14C]citric acid is formed stereoselectively. Note that citric acid containing only 12C is achiral. Assign an R or S configuration to this enantiomer of [2-14C]citric acid. (Note: Carbon-14 has a higher priority than carbon-12.)
