(a)
Interpretation:
Whether the given carbonyl group requires protection is to be determined.
Concept introduction:
The protecting groups are used to make the specific
(b)
Interpretation:
Whether the given carbonyl group requires protection is to be determined.
Concept introduction:
The protecting groups are used to make the specific functional group temporarily unreactive in a poly-functional group molecule under reaction conditions needed to make modifications in other functional group in the molecule. The protecting group can be removed once the desired reaction is carried out, and the original functional group is restored.
(c)
Interpretation:
Whether the given carbonyl group requires protection is to be determined.
Concept introduction:
The protecting groups are used to make the specific functional group temporarily unreactive in a poly-functional group molecule under reaction conditions needed to make modifications in other functional group in the molecule. The protecting group can be removed once the desired reaction is carried out, and the original functional group is restored.
