General description
2-(Trimethylsilyl)ethoxymethyl chloride (SEM-Cl) is a widely used reagent for the preparation protection groups for amines, alcohols, phenols, and carboxy groups. The nitrogen of amides and sulfonamides groups are also protected by using SEM-Cl reagent.
Application
SEM-Cl can be used as a reagent for the preparation of 2,4,5-trisubstituted tetrahydropyrans form homoallylic alcohols by a Prins-type cyclization reaction. It can also be used in the synthesis of amino acid SEM esters from N-protected amino acids in the presence of lithium carbonate.
Other Notes
Protecting-group reagent for alcohols and other functional groups selectively removable with Bu4NF ; Protecting group for pyrroles and imidazoles, facilitating selective metalation ; Reagent for the introduction of a protected C1 building block
