# What will the final product of this synthetic sequence be?

What is the major product formed in the following reaction?

NBS should do allylic bromination but where will it attack in the larger ring or smaller one ?

• @Zhe I still am not clear why allylic bromination doesn't take place. My thought process was as follows: 1. Co-ordination of bromine of NBS and $\pi-$bond. 2. Formation of bromonium carbocation, with succinimide as a nucleofuge. 3. Attack by water on the bromonium resulting in the anti-stereochemistry. 4. Deprotonation by the extra pair on the succinimide. Is this correct? – Eashaan Godbole Dec 22 '16 at 12:57
