Does anyone have a simple procedure for the hydrolysis of an amide? Is it easier with acid or base? I wasn't able to find much online... Hey mate, I just had a few more questions I was hoping you could help me with regarding the TBDMS reaction. You mentioned that you need an apro...
Moreover, all the above mentioned Pd(II) complexes were also able to catalyze the regioselective hydrolysis of the His–Gly amide bond of Ac–L–His–Gly dipeptide. However, in the reaction with Ac–L–His–Gly, only Pt(II) aqua complexes containing bridging ligands with two nitrogen atoms...

Intramolecular nucleophilic catalysis of amide hydrolysis by pyrimidine nitrogenRate constants and thermodynamic activation parameters have been determined for the intramolecular carboxyl-catalyzed hydrolysis of a series of 1-mono- and 1,1-disubstituted carboxy-N-methyl-N-phenylmethanesulfonamides 1-10. ...
Alright. Next, we're going to have yet another proton transfer where this sulfur is going to deprotonate this OH. Oxygen holds on to the electrons, so then we're going to get this neutral amide plus this thiol. Now remember, because of the acidity ...
The hydrolysis of a phosphinic acid ester is typically one of the final steps in the synthesis of such inhibitors. We have found that the acid-catalyzed hydrolysis of a phosphinic acid ester containing a β-carboxamido group is facilitated by the presence of the amide. The promotion of the ...
Changing the ester group in the readily hydrolyzed procaine to an amide and introducing aromatic methyl groups to hinder the attack of the carbonyl group significantly reduce the rate of hydrolysis. The resulting lidocaine is a longer-acting local anesthetic than procaine (Figure 32.1). Sign in to...
