allylprotected
Allyl protection refers to the temporary blocking of a functional group, typically a hydroxyl group, by attaching an allyl moiety. This is a common strategy in organic synthesis to prevent unwanted reactions at a specific site while transformations are carried out elsewhere in a molecule. The allyl group is chosen for its relative stability under a variety of reaction conditions and its ease of removal when no longer needed.
The allyl ether is formed by reacting the alcohol with an allyl halide, such as allyl bromide
Deprotection, the removal of the allyl group, is typically achieved through palladium-catalyzed reactions. Common methods include
