Two students are given 3-oxobutanoic acid below and asked to
prepare 2-methyl-3-oxobutanoic acid.
The first student recognizes this as the first step of the
acetoacetic ester synthesis. He treats the starting material with
sodium methoxide followed by methyl iodide. He isolates compound A,
but 1H NMR analysis shows this is not the desired material.
Elemental analysis shows it has the same molecular formula as the
2-methyl-3-oxobutanoic acid. What is compound A?
The second student recognizes an extra step is needed...
