The missing compounds A through D are to be supplied. Concept introduction: The starting amide undergoes hydrolysis to produce carboxylic acid , A . Diazomethane converts the carboxylic acid to a methyl ester. This methyl ester is reduced by the reducing agent DIBAH B to an aldehyde . This aldehyde undergoes direct addition by Grignard reagent to make alcohol C . The alcohol is then deprotonated to make the alkoxide anion, which is then acylated with acetic anhydride, yielding the target compound D .

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
