Establishment of salicylic acid derived silylation reagents for protection of alcohols
Results in Chemistry, 2021 In this work, we describe salicylic acid derived 2-[(trimethylsilyl)oxy]-benzoic acid methyl ester (TMSSME) and its TBDMS- (TBDMSSME) and TIPS-analogous (TIPSSME) as novel silylation reagents to furnish silyl ethers from alcohols.
