Using any reagents necessary, the given synthesis is to be carried out. Concept introduction: The target compound has four C atoms, and the starting material has three C atoms. The α,β- unsaturated aldehyde undergoes 1, 4-addition by NaCN to form nitrile. In hydrolysis reaction the nitrile is converted to carboxylic acid. The aldehyde is reduced to alcohol, which undergoes an acid-catalyzed intramolecular Fischer esterification reaction.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
