The fluorenylmethoxycarbonyl protecting group (Fmoc) is a base-labile amine protecting group used in organic synthesis, particularly in peptide synthesis. [1] It is popular for its stability toward acids and hydrolysis and its selective removal by weak bases, such as piperidine , without affecting most other protecting groups or sensitive ...

The Federal Open Market Committee (FOMC) consists of twelve members--the seven members of the Board of Governors of the Federal Reserve System; the president of the Federal Reserve Bank of New York; and four of the remaining eleven Reserve Bank presidents, who serve one-year terms on a rotating basis.

What is the Fmoc Protecting Group? Fmoc is a fluorenylmethoxycarbonyl group that forms carbamates with amines. However, as a common theme, alcohols and other nucleophiles can also be protected. Fmoc was introduced by Carpino in 1972 [1]. You will realize that this is pretty late in the game!

Fluorenylmethyloxycarbonyl chloride (Fmoc-Cl) is a chloroformate ester. It is used to introduce the fluorenylmethyloxycarbonyl protecting group as the Fmoc carbamate.

A simple and efficient protection procedure is general and regioselective for the preparation of mono-N-Boc, N-Cbz, N-Fmoc or N-Alloc aromatic amines in high yield without affecting aliphatic amino groups and other functionalities.

The development of the fluorenyl methoxycarbonyl protecting group (FMOC) and its move into organic synthesis methods represents a clear breakthrough in chemistry.

While the latter technology has continued to undergo further refinement and improvement in both its chemistry and automation, the development of the base-labile 9-fluorenylmethoxycarbonyl (Fmoc) group and its integration into current synthesis methods is considered a major landmark in the history of the chemical synthesis of peptides.

Reagent for derivatizing amino acids for HPLC amino acid analysis and for preparing N-Fmoc amino acids for solid-phase peptide synthesis.

The deprotection step is crucial in order to secure a good quality product in Fmoc solid phase peptide synthesis. 9-Fluorenylmethoxycarbonyl (Fmoc) removal is achieved by a two-step mechanism reaction favored by the use of cyclic secondary amines; ...

Fmoc resin cleavage and deprotection are crucial steps for peptide synthesis, yielding the desired peptide after resin detachment.
