TMSCl is reactive toward nucleophiles, resulting in the replacement of the chloride. In a characteristic reaction of TMSCl, the nucleophile is water, resulting in hydrolysis to give the hexamethyldisiloxane: 2 Me3SiCl + H2O → Me3Si-O-SiMe3 + 2 HCl The related reaction of trimethylsilyl chloride with alcohols can be exploited to produce anhydrous solutions … WebCarbon‐based solid acid was used as a new catalyst for conversion of trimethylsilyl ethers to their corresponding ethers in heterogeneous mixtures.

WebTrimethylsilyl (TMS) protecting group has been found to be very useful for the simultaneous protection of both the glycosyl donor- and the acceptor-substrates in oligosaccharide synthesis. Thus, while the per-O-trimethylsilylated glycosyl iodides served as the glycosyl donor, those bearing selectively exposed primary hydroxyl groups were found suitable as … WebThe process proceedes via α-cyanomethylation of dimethyl N-BocGlu in the presence of NdCl 3 , followed by one-pot Raney nickel-catalyzed hydrogenation of the cyano group with concomitant cyclization and ammonolysis and subsequent deprotection of N-Boc to deliver the target intermediate cyclic glutamine analog in three steps with an 82% overall yield …
