Amides are the most unreactive of all carboxylic acid derivatives. This is because of its slight double bond characteristic that reduces the leaving group ability of the nitrogen. This resonance form is more prevalent among amides than it is for carboxylic acids, esters, or anhydrides. Are ...
Interestingly, 16:1-CoA and 18:3-CoA are the predominant nuclear acyl-CoA species even though the levels of the correspondingfree fatty acidsare low in nuclei (13). This is not unprecedented as other studies clearly have shown that the cellular level of long-chain acyl-CoA esters does not...
No. 834,495 have become known 4 -(pyrid-2 -yloxy)-alkanecarboxylic acids and 4-(pyrid-2 -yloxy)-alkanecarboxylic acid esters both having a herbicidal action against grasses, but not against broad-leaved plants. And from the German Offenlegungsschrift No. 2,223,894 are known herbicidal...

Esters 17 are converted into their corresponding carboxylic acids of the formula Ia, using methods well known to someone skilled in the art, e.g. acid- or base-mediated ester hydrolysis. The reaction is typically carried out in solvents such as water, methanol, tetrahydrofuran, 1,4-dioxane ...
aPyridinium methanesulfonate (m.p. 185°C) and pyridinium p-toluenesulfonate (m.p. 121°C) were used as catalysts and media for the esterification of carboxylic acids with primary alcohols to give the corresponding esters selectively in high yields. The high melting points of these pyridinium sal...
Some examples of retarders are – sugar, lignin, hydroxylated carboxylic acids, phosphates, cellulose and so on. Some disadvantages of this includes that they increase plastic shrinkage often and result in cracking. Also, if addition time is delayed then retardation gets further extended. COURTESY:...
Typical prodrugs are phosphates, carbamates of aminoacids, esters and other compounds. [0291] The indole derivatives according to the invention can be prepared in a variety of ways. Possible methods of synthesis follow those described in the above-listed literature references. Scheme is intended ...
