Sulfonic acid amides

We conclude this section by noting that, as in the case of other acids, there are various sulfonic and sulfuric acid derivatives including esters and amides. Fig. 2.20 shows two examples of sulfonic acid amides that are representatives of important groups of drugs (sulfodiazine) and herbicides (sulfometuron), respectively. [Pg.49]

An important specificity in the catalysis was shown in dilute solutions of the sulfonic acids amide groups (—CO-NHa) were preferentially broken, the peptide bonds (—CO-NH-CHR—) proving more resistant. Steinhardt and Fugitt attributed this to the fact that, as slightly stronger bases, the amide groups successfully competed with the peptide bonds... [Pg.45]

BMB reduces only specific functional groups. In tetrahydrofiirane at 0° it reduces aldehydes and ketones to alcohols, -y-valerolactone (11) to y-hydroxyvaleraldehyde (12), and N,N-dimethylamides to aldehydes. Under the same conditions it does not reduce carboxylic acids, sulfonic acids, amides, esters, acid chlorides, anhydrides, or sulfones. The failure of the carboxyl group to react makes possible the conversion... [Pg.32]

Such a procedure has been exploited for the synthesis of several derivatives for which an anti-inflammatory activity has been claimed [58]. A derivative under study as the Histamine H3 antagonist was prepared by the thermal intramolecular Diels-Alder reaction of a triene derivative of buta-1,3-diene-1-sulfonic acid amide. 1,3-Butadiene sulfonamides 182 (a 67%, b 69%, c 99%, d 51%) were prepared by the base mediated condensation of M-Boc-methanesulfonamides (181) with a series of aldheydes. N-akylation of 182 to give trienes 183 (a 69%, b 76%, c 82%, d 59%) was achieved by reacting the sodium salts with allyl bromide in THF at reflux. The intramolecular Diels-Alder reactions of compounds 183 were performed at 145 °C in toluene in a sealed vessel under argon. Under these conditions compounds 184 and 184 were obtained in good yields (a 76% ratio 6 1, b 71% ratio 6 1, c 92% ratio 3 1, d 87% ratio 3 1). [Pg.208]

We selected carboxylic acid groups as the main component of weakly acidic cation exchange groups, rather than sulfonic acid amide with a dissociable hydrogen, phosphonic acid, phenolic hydroxide or perfluoro-tert-alcohol exchange sites, from the viewpoint of ease of preparation, stability and good performance in electrolysis,... [Pg.408]

Although perfluorocarbon sulfonic acid groups are very stable chemically as well as thermally, perfluorocarbon sulfonyl halide, especially sulfonyl chloride groups, are quite reactive. For example, sulfonyl chloride groups react with oxidants, reductants, various amines, phenol compounds, iodine compounds, etc. and give carboxylic acid, sulfinic acid, sulfonic acid amide, -CF2I and so forth. Some examples of how this feature can be used to generate various kinds of membranes will next be described... [Pg.408]
