A reaction sequence for the synthesis of the given compound has to be proposed. Concept Introduction: Reformatsky reaction: It states that the treatment of an α − haloester with zinc metal in the presence of an aldehyde or a ketone followed by hydrolysis in aqueous acid results in formation of a β − hydroxyester.

Question

The following compound may be synthesized through alkylation of an appropriate enamine with an alkyl bromide, followed by hydrolysis of the resulting immonium ion. Using this strategy, provide the necessary starting materials for the synthesis. (Note that a portion of the starting enamine is given.)

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.

The following compound may be synthesized through alkylation of an appropriate enamine with an alkyl bromide, followed by hydrolysis of the resulting immonium ion. Using this strategy, provide the necessary starting materials for the synthesis. (Note that a portion of the starting enamine is given.)

What explains why many aldehydes and ketones can undergo self-condensation reactions in basic conditions? The alpha carbon can lose a proton and act like a nucleophile and the carbonyl carbon is an electrophile. The alpha carbon can gain a proton and act like an electrophile and the carbonyl carbon is a nucleophile. The oxygen of the carbonyl group can attack the carbon of the carbonyl group. Only esters can undergo self-condensation reactions.
