The
first step is the formation of carbanion. I'm the next step, the
carbanion attack the aldehyde group and oxygen take proton to form
OH. When the product is heated enone is formed.
So the given product is not formed in Aldol condensation reaction.

1. Draw the aldol product formed from an aldol/Claisen reaction with the given starting material(s) using OH or RO in H20 or ROH. (Hint: the product of an aldol reaction is a B-hydroxy carbonyl compound or an a,b- unsaturated carbonyl compound. The a,ß-unsaturated carbonyl will be the major product unless elimination of H2O cannot form the conjugated system.) он Но, но Н,0 НО. ОН НО. он H, H НО. НО.

I
am trying to figure out the starting materials, solvent, and
reagent to form the product methyl-2-methyl-3-oxobutanoate. I can
choose from the following starting materials: Methyl acetate,
Methyl propionate, and 1,7-Dimethyl-heptanedioate. I can choose
EtOH or Et2O as a solvent. I can choose the reagents listed in the
picture provided. Which would be best to make the desired product
and what would the mechanism be?
