Trimethylsilyl ethanol

Web2-(Trimethylsilyl)ethanol is used as a protecting reagent for carboxyl, phosphoryl, hydroxyl and amino group in organic synthesis. It is used as a precursor to prepare trimethyl(2-phenoxyethyl)silanes by reacting with aromatic fluoride. It is also used in the synthesis of teoc-protected amines by using the corresponding isocyanates. WebMay 16, 2013 · Four novel 2-(trimethylsilyl)ethyl glycosides have been synthesized by a short and efficient route starting from d-glucose. Their structures were elucidated by applying high-resolution mass spectra, and one-dimensional and two-dimensional NMR techniques. These glycosides were prepared and used as intermediate building blocks in …
