2-Arylallyl as a new protecting group for amines, amides and alcohols.

Amines, amides and ethers containing 2-arylallyl groups are selectively and easily deprotected with tert-butyllithium. This transformation probably involves a carbolithiation reaction of the styrenyl moiety followed by a beta-elimination process.

2-Hydroxyphenacyl ester: a new photoremovable protecting group.

A 2-hydroxyphenacyl moiety absorbing below 370 nm is proposed as a new photoremovable protecting group for carboxylates and sulfonates. Laser flash photolysis and steady-state sensitization studies show that the leaving group is released from a short-lived triplet state. In addition, DFT-based quantum chemical calculations were performed to determine the key reaction steps. We found that triple...

Gold oxide as a protecting group for regioselective surface chemistry.

Selective modification of electrode surfaces is a vital step in the development of many practical applications of self-assembled monolayers (SAMs). This paper describes a protection-deprotection strategy similar to that commonly utilized in organic synthesis, with gold oxide as a protecting layer, to direct self-assembly on one gold electrode in the presence of another.

Understanding Tetrahydropyranyl as a Protecting Group in Peptide Chemistry

Tetrahydropyranyl (Thp) is recognized as a useful protecting group for alcohols in organic synthesis. It has several advantages, including low cost, ease of introduction, general stability to most non-acidic reagents, it confers good solubility, and the ease with which it can be removed if the functional group it protects requires manipulation. However, little attention has been paid to Thp in ...

Tetraisopropyldisiloxane-1,3-diyl as a versatile protecting group for pentopyranosides.

The protecting group tetraisopropyldisiloxane-1,3-yl has been investigated for simultaneous protection of two hydroxyls on pentopyranosides. Methyl α-D-xylopyranoside is protected in excellent regioselectivity and high yield to form the 2,3-protected xylopyranoside whereas methyl β-D-xylopyranoside gives the 3,4-protected product also with excellent regioselectivity.
