silylprotecting
Silyl protecting refers to the use of silyl ethers to temporarily mask hydroxyl groups in organic molecules, and occasionally to stabilize other functionalities during complex sequences. This strategy allows selective reactivity elsewhere in a molecule, enabling multi-step syntheses without protecting groups that are harder to remove or incompatible with subsequent steps.
Installation of a silyl protecting group typically involves reacting the alcohol with a silyl chloride or
Deprotection is often achieved with fluoride sources, such as tetra-n-butylammonium fluoride (TBAF), HF-pyridine, or CsF, in
Applications of silyl protecting groups span carbohydrate chemistry, natural product synthesis, and medicinal chemistry. Considerations when
