  • tert-Butyldimethylsilyl Ethers - Organic Chemistry Portal
    Various silyl ethers were readily and efficiently transformed into the corresponding alkyl ethers in high yields by the use of aldehydes combined with triethylsilane in the presence of a catalytic amount of iron (III) chloride
  • Application Note Protocol: One-Pot Oxidation of Primary TBS Ethers to . . .
    Several effective methods have been developed for the one-pot oxidation of primary TBS ethers to aldehydes Below, we detail some of the most robust and widely adopted protocols
  • tert-Butyldiphenylsilyl - Wikipedia
    The tert -butyldiphenylsilyl group was first suggested as a protecting group by Hanessian and Lavallée in 1975 It was designed to supersede the use of Corey's tert -butyldimethylsilyl as a protecting group for alcohols:
  • Tosylates And Mesylates – Master Organic Chemistry
    As they contain a good leaving group, alkyl tosylates or mesylates can perform all of the substitution and elimination reactions of alkyl halides A few examples are shown below Get familiar with MsCl and TsCl in both their abbreviated and expanded (i e “drawn-out”) forms
  • Protecting Groups For Alcohols - Master Organic Chemistry
    The original paper by Nobel Laureate Prof E J Corey (Harvard) describing convenient conditions (TBS-Cl, DMF, imidazole) for the protection of alcohols as TBS-ethers
  • The Enduring Guardian: A Technical Guide to the Mechanism of TBS . . .
    This in-depth technical guide provides a comprehensive exploration of the mechanism of TBS protection, supported by quantitative data, detailed experimental protocols, and visual representations of the core chemical transformations and workflows
  • Where does the aldehyde group usually attach during the Reimer-Tiemann . . .
    Alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids The oxidation of organic compounds generally increases the number of bonds from carbon to oxygen, and it may decrease the number of bonds to hydrogen (more) In the Reimer-Tiemann reaction, the aldehyde group typically attaches to the ortho position of the phenol ring
  • Protecting Groups - University of Chicago
    In practice this concept is incredibly difficult to reduce to practice, but it is a useful framework and organizing principle to think about protecting group regimes for a complex molecule synthesis
  • tert-Butyldimethylsilyl chloride - Wikipedia
    tert-Butyldimethylsilyl chloride is an organosilicon compound with the formula (Me 3 C)Me 2 SiCl (Me = CH 3) It is commonly abbreviated as TBSCl or TBDMSCl It is a chlorosilane containing two methyl groups and a tert -butyl group As such it is more bulky than trimethylsilyl chloride
  • Alcohol Protecting Groups — Organic Chemistry Tutor
    What’s important about this protecting group is that it’s bulky and chemically resilient However, we can easily take it off using hydrogen on palladium catalyst
