Vedclass · Answer

(B) The reaction involves the nucleophilic attack of the primary amine $(R-CH_2-NH_2)$ on the carbonyl carbon of the lactone ring. This leads to the ring-opening of the lactone,forming an amide intermediate. Subsequently,the nitrogen atom of the newly formed amide attacks the other carbonyl group (or the electrophilic center generated by the leaving group) to close the ring,resulting in the formation of a lactam derivative with a hydroxyl group. The final product $(A)$ is the structure shown in option $(B)$.

In the above reaction,identify the major product $(A)$ of the reaction.
