What is the product of the following reaction with NaBH4?
Understand the Problem
The question is asking us to predict the product of a given reaction. The starting material is a cyclic ester/acid chloride, and the reagent is NaBH4, a reducing agent. We need to select from the given options the correct product after the reduction.
Answer
The final answer is (A)
The product of the reaction with NaBH4 is (A). NaBH4 will reduce the carbonyl groups to alcohols.
Answer for screen readers
The product of the reaction with NaBH4 is (A). NaBH4 will reduce the carbonyl groups to alcohols.
More Information
NaBH4 is a reducing agent that selectively reduces ketones, aldehydes, and acyl chlorides to alcohols. It does not reduce esters.
Tips
Common mistake is reducing the ester. In this case only the carbonyl groups and the acyl chloride are reduced to alcohols.
