Factors governing choice of protecting groups

The search for suitable protecting groups of carbonyl and hydroxyl functions has been of continuous importance in steroid chemistry. As a result of these efforts a good selection of protecting groups is now available for use in organic synthesis. 

When only one carbonyl or hydroxyl group is to be blocked in a multifunctional compound, the choice of the protecting group will be determined by the ease with which the group can be introduced selectively into the parent molecule.
