Interpretation:
A multi-step synthesis has to be designed for the given conversion.
Concept Introduction:
Target molecule is nothing but the desired product.
Adding
The elimination reaction should be carried out under SN2 condition i.e. with strong nucleophile. So there will be no compensating substitution reaction.
The bulky base is used in the elimination reaction to maximize the amount of elimination product.
To prepare cyclic ether, the
Addition of water to the given starting material creates bifunctional compound.
