What is the purpose of using benzyl chloroformate in the synthesis of 2-deoxy-2-amino-C-glycoside?

Label:chem

Topic
A study mentions the use of benzyl chloroformate in the protection step of the synthesis process.
Answer
Benzyl chloroformate is used to protect the free amine group in the intermediate compound 11. It reacts with the amine to form a benzyloxycarbamate group, ensuring that the amino functionality remains intact during subsequent synthetic steps.
