ACETYLATION OF AROMATIC AMINES Acetyl derivatives of aromatic amines may be prepared either with acetic anhydride or acetic acid or with a mixture of both reagents. Primary amines react readily upon warming with acetic anhydride to yield, in the first instance, the mono-acetyl derivative, for example ... [Pg.576]

Hydrazine is a colorless oily liquid that fumes and is flammable. Absorption occurs by all routes of administration. Several possible metabolic pathways exist for hydrazine and include hydrolysis, acetylation, and the splitting of hydrazine into two equal amines. Acetylation appears to have a major role in humans and slow acetylators may be more susceptible to toxic effects. Hydrazine and its metabolites are excreted by the kidneys. [Pg.1347]

The strategy employed for synthesizing compounds such as (45) started with shikimic acid (47) and employed the aziridine derivative (48) as the key intermediate (Scheme 1.5) [120]. Exposure of the aziridine (48) to alcohols in the presence of BF3-Et20 and subsequent amine acetylation gave... [Pg.19]

CoA involved many simultaneous approaches. Many years were spent in unraveling the tangle of information obtained from studies on microbial nutrition, enzyme reactions (in addition to amine acetylation) that require CoA, yeast oxidation of acetate, and degradation and synthesis of the cofactor. The results of these studies are summarized in the following sections. [Pg.71]

Amine Acetylation. The first acetylation reaction to be studied intensively was the acetylation of aromatic amines, of which sulfanilamide was used as a representative (II). This system was used for the first assays of CoA. The amine-acetylating enzyme has been partially purified. [Pg.88]

The loss of acetyl CoA was found to be caused by a nonenzymatic transfer of acetyl groups to other sulfhydryl compounds added to the system. Ordinarily sulfhydryl compounds should not be required in reactions of acetyl CoA, as opposed to systems using free CoA, whose —SH group needs protection. But the amine-acetylating enzyme also has essential —SH groups that require protection. The dilemma was... [Pg.89]

Choline acetylase and the amine-acetylating enzyme are distinct, and do not cross react with the substrates of the other enzyme. [Pg.369]
