Triethylsilyl
WebProtection & deprotection contitions for the Triethylsilyl ether (TES) protecting group. WebSynthetic methods have been previously disclosed in scientific and patent literature. Three different routes for synthesizing paclitaxel known in the literature are discussed hereinbelow. The first two routes utilize 7-O-TES (triethylsilyl) accatin III 4, obtained from the selective silylation and cetylation of 10-DAB.
