A variation of the acetamidomalonate synthesis can be used to synthesize threonine. The process involves the following steps: Et

hoxide ion deprotonates diethyl acetamidomalonate, forming enolate anion 1; Enolate anion 1 makes a nucleophilic attack on acetaldehyde, forming tetrahedral intermediate 2; Protonation of the oxyanion forms alcohol 3; Acid hydrolysis yields dicarboxyamino alcohol 4; Decarboxylation leads to the final amino acid. Write out the mechanism on a separate sheet of paper, and then draw the structure of tetrahedral intermediate 2.

Answer:

See figure 1

Explanation:

For this reaction, we have the production of a carbanion as the first step. The base "ethoxide" can remove a hydrogen-producing a negative charge in the carbon (<u>enolate anion 1</u>). Then this negative charge can attack the carbon of the carbonyl group in the molecule acetaldehyde and the <u>tetrahedral intermediate 2</u> is form. In the next step, we have the protonation of the oxygen to produce <u>alcohol 3</u>. A continuation we have the hydrolysis of the ester groups to produce the <u>Dicarboxyamino alcohol</u> and finally, we have a decarboxylation reaction we will produce the amino acid <u>Threonine</u>.

To further explanations see figure 1

I hope it helps!

What causes atoms to share electrons equally with atoms, but unequally share with others?
Minchanka [31]

Answer:

Atoms only share electrons in covalent bonds. covalent bonds are only formed between nonmetals. there are two different types of covalent bonds; polar and nonpolar. in a polar covalent bonds electrons are shared unequally because one atom has a stronger force of attraction than the other (EX. H2O). In a nonpolar covalent bond, the electrons are shared equally because they're electronegativity is also equal (EX. Cl2).

Overall, the atoms electronegativity determines the way it shares electrons
