What product or products are obtained when d-galactose reacts with each of the following?
a. nitric acid + ∆ b. Ag+, NH3, HO- c. NaBH4, followed by H3O+ d. excess CH3I + Ag2O e. Br2 in water f. ethanol + HClg. 1. hydroxylamine/trace acid
2. acetic anhydride/∆
3. HO-/H2O
Trehalose, C12H22O11, is a nonreducing sugar that is only 45% as sweet as sugar. When hydrolyzed by aqueous acid or the enzyme maltase, it forms only d-glucose. When it is treated with excess methyl iodide in the presence of Ag2O and then hydrolyzed with water under acidic conditions, only 2,3,4,6-tetra-O-methyl-d-glucose is formed. Draw the structure of trehalose
The carbonyl group in d-galactose may be isomerized from C1 to C2 by brief treatmentwith dilute base (by the enediol rearrangement, Section 23-7). The product is the C4epimer of fructose. Draw the furanose structure of the product.
