  • Carboxylic acid derivatives are compounds with functional groups that can be converted to carboxylic acids by a simple acidic or basic hydrolysis. They include esters, amides, nitriles, acid halides, and acid anhydrides.
  • Reaction of -OH and -COOH on same molecule produces a cyclic ester, lactone.
  • Esters are named as alkyl carboxylates.Alkyl from the alcohol, carboxylate from the carboxylic acid precursor.
  • Acyl intermediates include acyl anions, acyl radicals and acyl cations (synonym: acylium ions) which are formally derived from oxoacids RkE(=O)l(OH)m (l not equal to 0) by removal of a hydroxyl cation HO+, a hydroxyl radical HO. or a hydroxyl anion HO-, respectively, and replacement analogues of such intermediates.
  • The reaction of a carboxylic acid and an alcohol yields an ester and water is eliminated.
  • A recent synthesis (4) made S-alkyl thiohydroxamic acids readily available, though in every case only one isomer, inferred to be the anti form, was isolated.
  • Active N-acyl, derivatives of a-amino acids are rapidly racemized by acetic anhydride at room temperature.
  • Acyl derivatives of ara-C4 with long linear saturated fattyacids at the A/4 position of ara-C exhibited a higher antitumor activity than did ara-C in the mouse leukemia L1210 system.
  • A large number and wide variety of acyl derivatives of the tylosin-related macrolides 23-demycinosyltylosin (DMT), 23-demycinosyloxytylosin DMOT) and 5-O-mycaminosyltylonolide (OMT) were synthesized and evaluated.
  • Analysis of the kinetics of hydrolytic and other transacylation reactions catalyzed by a-chymotrypsin yields two kinds of kinetic parameters.
  • Acylation is one of the fundamental reactions in organic chemistry and can be carried out by wide variety of reagents. Acyl groups play an important role in the chemistry of biomolecules.
  • Ester enolates which is a derivative of corboxylic acid derived from alkyl esters of alkanoic acids react with carbony1 compounds in an aldol type reaction forming alkyl @-hydroxyalkanoates.
  • N-alkylation, N-acylation, and Nhydroxyacylation, type of organic compound used in each of N-substitution reactions to ultimately enhance the bioactivity of chitosan.
  • The ideal acylating reagent would be a carboxylic acid, but the acids themselves are relatively unreactive with nucleophiles. A simple solution to this inactivity, as noted earlier, was to convert the carboxylic acid to a more reactive derivative such as an acyl chloride or anhydride.
  • Chiral phase HPLC has mainly been applied to pharmaceutical molecules but Chapter 7 shows how it can be used to separate enantiomers of monacyl and diacylglycerols.
  • The development of acyl derivatives was determined by borohydride reduction technique.
  • Polybutadiene with a narrow molecular weight is synthesized by anionic polymerization of butadiene monomer in cyclohexane at 20 ' C using
    n-butyllithium as Initiator .The amount of urazole and acyl incorporation are determined by 1H NMR technique.
