【Abstract】 The characteristics, protective principle and application of Sterically hindered silane blocking agents were reviewed. Organochlorosilane is widely used in the protection of organic functional groups involving hetero atoms, such as hydroxyl, carboxyl, carbonyl, amino group and so on .The conditions of protection and deprotection and the application development in the synthesis of pharmaceuticals are given in the article. Its trend of development is viewed in this article.更多还原
