Reagents needed to convert A to naproxen using enolate alkylation are to be predicted. The reason for the formation of a racemic product is to be stated. Concept introduction: Alkylation of aldehydes and ketones takes place in the presence of a strong base. The use of appropriate base, solvent and temperature can yield one major product regioselectively.

Question

Identify A, B, and C, three intermediates in the synthesis of the pain reliever and anesthetic fentanyl.

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.
