The mechanism of action in peptide synthesis involves the protection and deprotection of the amino acid residues, allowing for the stepwise assembly of the peptide chain. Storage Conditions: Store in a cool and dry place. View all 4. Safety and Handling4.1 Specification N-Boc-N'-Fmoc-D-2...
It is commonly used as a building block in solid-phase peptide synthesis, offering a reliable method for the protection and deprotection of amino acids. FMOC-D-PHG-OH provides stability to the peptide chain during synthesis and can be easily removed after peptide assembly. This compound plays a...
Allylation of 6-chloro-2-aminopurine followed by acid hydrolysis, Cbz protection with N -(benzyloxycarbonyl)imidazole, ozonolytic cleavage, and oxidation afforded the Cbz-protected guanine acetic acid ( 5 ). The base acetic acids ( 2, 3, 4 and 5 ) were coupled to the backbone ( 1 ) with...
去FMOC⽅法研究(转载)The electron withdrawing fluorene ring system of the 9-fluorenyl-methyloxycarbonyl (Fmoc) group renders the lone hydrogen on the β-carbon very acidic and, therefore, susceptible to removal by weak bases (1, 2). Following the abstraction of this acidic proton at the 9...

and imidazole ring must be protected.Because of Fmoc group's some specific virtues,like its instability to alkali and the nature of easy to be detected,we chose Fmoc as the α-NH_2 protecting group.In Fmoc strategy,trityl was stable to the conditions of coupled action and deprotection.It ...
The combined use of Fmoc (fluorenylmethoxycarbonyl) as N-protection and Tmse (trimethylsilylethyl) as O-protection during demanding fragment condensation mediated by Bop-Cl (N, N′-bis(3-oxo-2-oxazolidinyl)phosphinyl chloride) has been explored in the preparation of useful synthons that are ...
