Vedclass · Answer

(A) The reaction involves the acid-catalyzed rearrangement of a spiro-dienone system. $1$. Protonation of the carbonyl oxygen occurs to form a resonance-stabilized carbocation. $2$. $A$ ring expansion occurs where the cyclobutane ring expands to form a six-membered ring,resulting in a more stable aromatic system. $3$. Deprotonation leads to the formation of $5,6,7,8$-tetrahydronaphthalen-$1$-ol (or a similar naphthol derivative). Based on the provided options and the mechanism shown in the solution image,the final product is a naphthol derivative. The structure corresponds to $5,6,7,8$-tetrahydronaphthalen-$1$-ol.
