Vedclass · Answer

(A) The reaction is a Stork enamine alkylation followed by hydrolysis. $1$. The enamine formed from cyclohexanone and $4$-methylpiperidine acts as a nucleophile. $2$. It undergoes a Michael addition with the nitroalkene ($1$-nitropropene). $3$. The nucleophilic carbon of the enamine attacks the $\beta$-carbon of the nitroalkene. $4$. Subsequent acid-catalyzed hydrolysis $(H_3O^+)$ converts the enamine back into a ketone,resulting in the $\alpha$-alkylation of the cyclohexanone. $5$. The product is $2$-($1$-nitropropan$-2-$yl)cyclohexanone,which corresponds to option $(A)$.
