7) Mannich reaction is an example of
A) Linear synthesis
B) Convergent synthesis
C) Saytzev's rule
D) Multi component synthesis
Answers
Answer:
The answer is Saytzev's rule ☺☺☺
Answer:
Through a series of elementary reactions, multicomponent reactions (MCRs) are synthetic processes that yield a single product from three or more reactants in a single pot.
Explanation:
Mannich reaction is nucleophilic addition. The condensation reaction is another name for the Mannich reaction.
It involves the condensation of a non-enolized aldehyde and an enolized carbonyl group (such as formaldehyde).
The reaction between primary, secondary, or ammonia and formaldehyde produces the iminium ion. By tautomerization, a carbonyl compound transforms into an enol form. The reaction is then advanced by the compound's enol form, which contains a carbonyl group.
Formation of Mannich Base: In the next step, the carbonyl compound's enol form attacks an iminium ion to produce an amino carbonyl compound, also known as a Mannich base.
Formaldehyde, a primary or secondary amine, or ammonia are used in the three-part organic reaction known as the Mannich reaction to amino alkylate an acidic proton next to a carbonyl functional group.
Hence, the correct option is (D) Multi-component synthesis.
