Question

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

Ethoxide ion deprotonates diethyl acetamidomalonate, forming enolate anion 1;
Enolate anion 1 makes a nucleophilic attack on formaldehyde, 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.

You do not have to consider stereochemistry.
You do not have to explicitly draw H atoms.
Do not include lone pairs in your answer. They will not be considered in the grading.
Draw carboxyl and amino groups in their uncharged forms.
