Here are the essential concepts you must grasp in order to answer the question correctly.
Tosylate Formation
Tosylate formation involves converting an alcohol into a tosylate ester using tosyl chloride (TsCl) in the presence of a base like pyridine. This transformation makes the hydroxyl group a better leaving group, facilitating subsequent nucleophilic substitution reactions. Tosylates are useful intermediates in organic synthesis due to their enhanced reactivity compared to alcohols.

Nucleophilic Substitution
Nucleophilic substitution is a fundamental reaction in organic chemistry where a nucleophile replaces a leaving group in a molecule. In the context of tosylate formation, the tosylate group acts as a superior leaving group, allowing for efficient substitution by various nucleophiles. Understanding the mechanism, whether SN1 or SN2, is crucial for predicting the outcome of the reaction.

Multistep Synthesis Strategy
Multistep synthesis involves planning and executing a series of chemical reactions to transform starting materials into a desired product. It requires understanding the reactivity and compatibility of functional groups, as well as the order of steps to maximize yield and efficiency. Each step must be carefully chosen to ensure the overall synthesis proceeds smoothly, often using intermediates like tosylates to facilitate transformations.
