Why is Product 238902 2-(Trimethylsilyl)ethoxymethyl chloride, such a popular hydroxyl protecting agent?
2-(Trimethylsilyl)ethoxymethyl chloride is widely used in the protection of alcohols because the SEM ethers are easily prepared. They are stable to a number of synthetic transformations, and they are easily removed.
What are the advantaged of using Product 238902, 2-(Trimethylsilyl)ethoxymethyl chloride, in carbohydrate chemistry?
In carbohydrate chemistry, the SEM group has shown distinct advantages over other groups such as the 2-methoxyethoxymethyl (MEM) group, because the SEM group is removed under milder acidic conditions.
Are SEM protected carboxylic acids like Product 238902 stable enough for chromatography?
SEM protected carboxylic acids are stable enough for chromatography but are readily deprotected without affecting either acid of base-sensitive functionalities.
How is the SEM group, Product 238902, 2-(Trimethylsilyl)ethoxymethyl chloride, used in the protection of nitrogen atoms in heterocyclic compounds?
In SEM protected indole, the aminal oxygen is used to direct lithiation to the 2-position. A similar approach has been used for pyrroles and imidazoles.
