(a) Interpretation: Complete mechanism for protection and deprotection of the following is to be proposed. Concept introduction: Protection of alcohol can be done using MOM (Methoxymethyl). These groups are stable in basic condition and hence can be deprotected in acidic condition. Formation of acetate structure makes them stable under basic condition, and hence they can be deprotected under acidic condition.
