In this case, hydrogenation not only reduced the double bonds in the polymer backbone, but also removed the protecting group, yielding the final polymer.
The formation of N-protected secondary amide bonds bearing the N-p-methoxybenzyl N-p-methoxybenzyl N-p-methoxybenzyl intermediates in common orgroup solvensuredd enabled purificathen by chromatography; boiling trifluoroacetic acid removed the protecting group in the final solubilityhe synthesis.
In order to introduce ionic bonds into traditional surfactant-like peptide to develop self-assembling materials with better properties, a catanionic surfactant-like peptide A6K± was designed by removing the protecting NH2 at the C-terminus of the cationic surfactant-like peptide A6K.
The following step was to selectively remove the Dde protecting group from the d-Lys amino acid residue by mixing the Rink amide MBHA bound protected linear BKT140 peptide with 2% hydrazine in DMF.
"The resolution suggests that Israel should remove the shield protecting its citizens, while doing nothing tangible about terrorism," said Dore Gold, an adviser to Israel's prime minister, Ariel Sharon.
In the area immediately surrounding an active electrode (anode), the amount of acid produced exceeds the amount of base present, and the generate acid is of sufficient strength to remove the DMT protecting group.
These crude products were treated directly with TFA/water to remove the Boc protecting group from the amino function of the linker moiety.
The resin was then treated with 1.8% TFA in dichloromethane for 30 s, repeated nine times(26) to selectively remove the Mtt protecting group on Lys.
Fifty mL of 2N hydrochloric acid was added to remove the dioxolane protecting group, and the mixture was stirred using a magnetic stirrer.
