Formation of amides substituted with hydroxyalkylacids by reaction in the presence of an acid catalyst of the amide and an aldehyde-aciddoi:US4956495 AA process for preparing unsaturated nitrogen containing acids such as acrylamidoglycolic acid utilizes a catalyst free route and low pH conditions. ...
Scheme 4. Proposed mechanism for the reaction catalyzed by HDAC8. Inhibitors for HDACs include a variety of compounds that interact with the Zn(II) center.233,273,274 Hydroxamate-containing inhibitors are well known,262 with suberoylanilide hydroxamic acid (SAHA) being the first HDAC inhibitor app...

The reaction of a 2-pyridylthiol ester with a dimethylaluminum amide leads to the rapid formation of the corresponding amide. The tolylthiol esters can be activated with silver trifluoroacetate and coupled even with poorly reactive amino compounds. 关键词: rhodium(II) carbenoid asymmetric synthesis ...
Sodamide, sodamine, NaNH2, white solid, formed by reaction of sodium metal and dry NH3 gas at 350 °C (662 °F), or by solution of the metal in liquid ammonia. Reacts with carbon upon heating, to form sodium cyanide, and with nitrous oxide to form sodium azide, NaN3. General Desc...
Amides are important intermediates in organic chemistry and the pharmaceutical industry, but their low reactivity requires catalysts and/or severe reaction conditions for esterification. Here, a novel approach was devised to convert amides into esters wi

β-Hydroxy alkylamide reacts with carboxylic acid to form an ester much faster than with a normal alcohol. Many suggestions have been made to describe the mechanism of this reaction, but none of them have been proved. It is clear that this reaction cannot be seen as a normal esterification...

194 latter and diamine can produce PAI.20 The second route goes through the imide-forming reaction, with amide- containing monomer serving as a medium; for example, amide-containing diamine is polycondensed with dian- hydride to provide the poly(amide amic acid), which is then dehydrated to ...
