应用
2-Methoxyethoxymethyl chloride, is used as selectively cleaved under aprotic conditions in the presence of a wide range of OH-protected reagents. It is used as an OH-protecting reagent. An examples of the target molecule MEM Chloride is the side chain of roxithromycin. It is also used in the protection of the OH groups in serine and threonine during peptide synthesis. Some of the other applications include have the ability to coordinate to metals, which is thought to accelerate the cleavage by Lewis acids. The chelating ability of the MEM ether also makes it useful as a stereodirecting group in organometallic reactions, first noted in the stereo controlled addition of ?-methoxyvinyllithium to a carbonyl in the synthesis of taxusin.
