Silane, 2-(chloromethoxy)ethyltrimethyl-: Does not have an individual approval but may be used under an appropriate group standard
使用2-(Trimethylsilyl)ethoxymethyl Chloride is a reagent used in the protection of alcohols, secondary aryl amines, and imidazole, indole, and pyrrole nitrogens;electrophilic formaldehyde equivalent; acyl anion equivalent,used in One-carbon Homologations, Cyclizations etc.
一般的な説明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.
純化方法Dissolve SEMCl in pentane, dry it (MgSO4), evaporate and distil the residual oil in a vacuum. Stabilise it with 10ppm of diisopropylamine. Store it under N2 in a sealed container in a refrigerator. [Lipshutz & Pegram Tetrahedron Lett 21 3343 1980.]
