Application
Phenol protecting group in the synthesis of laterifluorones.1
Used to prepare a SEM-ether which was, in turn, removed with BBr3 and cyclized to a benzo-oxapane.
Features and Benefits
Convenient hydroxyl-protecting reagent. SEM-ethers are stable over a wide pH range, and can be selectively cleaved with fluoride ion under mild aprotic conditions.2,3
Packaging
