Ethers, 1-ethoxyethyl alcohol protection

As an alternative to protection as ethers, alcohols can also be protected as acetals, the most common being tetrahydropyranyl ethers (THP-OR) and 1-ethoxyethyl ethers (EE-OR) (Table 7.7). Support-bound secondary aliphatic alcohols have been... [Pg.222]

As a similar protecting function the 1-ethoxyethyl ether, formed by reaction of the alcohol with ethyl vinyl ether, was introduced (Scheme 28). It displayed advantageous properties for the construction of oligonucleotides since it could be cleaved with 5% acetic acid without affecting the intemucleotide bond. ... [Pg.649]
