Clear Colourless Liquid | [Uses]
3-(T-butyldimethylsiloxy)propanol is primarily used as a protective group in organic synthesis, specifically for protecting alcohol or phenol functional groups. It can also act as a coupling agent, adhesion promoter, and forms periodic mesoporous silicas. | [General Description]
3-((tert-Butyldimethylsilyl)oxy)-propanol (3-[(tert-butyldimethylsilyl)oxy]-1-propanol) is formed as an intermediate during the synthesis of 3-(tert-butyldimethylsilyl)oxy]propanal. | [Synthesis]
The general procedure for the synthesis of 3-(tert-butyldimethylsilyloxy)propanol from tert-butyldimethylchlorosilane and 1,3-propanediol is as follows: this synthesis has been reported in the literature as part of the exemplary "bottom fragment "15 for the preparation of dictyostatin and its analogs. Specifically, 1,3-propanediol is converted in nine steps to the known bis-TBS-protected Homer-Wadsworth-Emmons product by an Evans chirality-assisted method.10 For related literature, see Phukan, P.; Sasmal, S.; Maier, M.
