Triethylsilyl
WebThe final step of the semisynthetic route to paclitaxel involves cleavage of the triethylsilyl (TES) protecting group from the C-7 hydroxyl group. Paclitaxel is an extremely complex molecule, and standard deprotection conditions led to formation of several impurities. WebProline is a bifunctional catalyst, acting as both Brønsted acid or base, or exhibiting both behaviors in the course of a mechanism. BOC Sciences possesses advanced laboratory equipment and unique R&D expertise to support the development and manufacture of multiple chiral compounds.

WebSep 5, 2011 · Therefore, we tested three trialkylsilyl groups (trimethylsilyl (TMS), triethylsilyl (TES), and triisopropylsilyl (TIPS)) as protection for the acetylene at position 7 of 7-deaza-2’deoxyadenosine. The synthesis and deprotection was first studied on model nucleoside monophosphates (see the Supporting Information for details).
