General information

Protecting Groups

Today, protecting groups have become an important tool in the multistep, organic synthesis of complex compounds. The task of a protecting group is to protect a functional group from undesirable reactions with other functional groups. Then the protecting group should be cleaved under as mild conditions as possible. Good protecting groups should be specific, highly selective and both introduceable and cleavable in high yields, and stable under as many reaction conditions as possible.
