Protecting Groups in Carbohydrate Chemistry | Journal of .
The most important protecting groups in carbohydrate chemistry are reviewed. The paper is aimed at those beginning to specialize in synthetic carbohydrate chemistry and at teachers with other specialties who wish to go beyond the content of general organic chemistry textbooks. Acetals and ketals are of fundamental importance in carbohydrate chemistry and their chemistry is presented first.
Protecting Groups List
Select a protective group to get the conditions needed to install/remove the group. Several reaction samples of protection and deprotection are shown for each groups. All of theses reactions are taken from our synthesis database and the list is continually growing.

Silyl Protective Groups | Chem-Station Int. Ed.
General Characteristics-Serving as effective protective groups for alcohols, silyl ethers are used extensively in laboratory scale synthesis.-At least two of the three R' groups are the same group, because if all three were different the silicon atom would be stereogenic and could give rise to diastereomers, which would complicate handling of the compound.
Protecting Groups For Alcohols – Master Organic Chemistry
7. Summary: Protecting Groups For Alcohols. This post barely scratches the surface of protecting groups for alcohols. Protecting groups are used for alcohols in a variety of different situations, far beyond the S N 2 examples we covered here. For instance, when we talk about Grignard reagents, we'll see that they can't be formed in the .
