The structure of the product that is formed if the given reactant undergoes intramolecular aldol condensation is to be explained. Concept introduction: Aldol condensation is a specific type of condensation reaction that is taken place only those carbonyl compounds that have alpha hydrogen with them. In this reaction, first, there is the formation of an enol or an enolate ion that ultimately attacks the carbonyl group of another molecule to form a beta hydroxy ketone .

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.

2-Ethyl-1-hexanol was needed for the synthesis of the sunscreen octyl p-methylcinnamate. Show how this alcohol could be synthesized (a) by an aldol condensation of butanal and (b) by a malonic ester synthesis starting with diethyl malonate.

The Stork reaction is a condensation reaction between an enamine donor and an α,β-unsaturated carbonyl acceptor. The overall reaction consists of a three-step sequence of formation of an enamine from a ketone, Michael addition to an α,β-unsaturated carbonyl compound, and hydrolysis of the enamine in dilute acid to regenerate the ketone. Consider the Stork reaction between cyclohexanone and propenal Draw the structure of the product of the enamine formed between cyclohexanone and dimethylamine. - Michael addition to an α,β-unsaturated carbonyl compound, and - hydrolysis of the enamine in dilute acid to regenerate the ketone.
