A similar concept was used in the development of artificial chymotrypsin mimics [54]. The esterase-site was modeled by using the phosphonate template 75 as a stable transition state analogue (Scheme 13.19). The catalytic triad of the active site of chymotrypsin - that is, serine, histidine and aspartic acid (carboxy-late anion) - was mimicked by imidazole, phenolic hydroxy and carboxyl groups, respectively. The catalytically active MIP catalyst 76 was prepared using free radical polymerization, in the presence of the phosphonate template 75, methacrylic acid, ethylene glycol dimethacrylate and AIBN. The template removal conditions had a decisive influence on the efficiency of the polymer-mediated catalysis, and best results were obtained with aqueous Na2CC>3. [Pg.444]

Radicals from Carboxylic Acids. Carboxy radicals appear to be involved in three venerable reactions in preparative carbohydrate chemistry, the Ruff degradation, the Hunsdiecker reaction and the Kolbe electrolysis. [Pg.690]

Amides are sometimes prepared directly from carboxylic acids and amines by a two step process The first step is an acid-base reaction m which the acid and the amine combine to form an ammonium carboxylate salt On heating the ammonium carboxy late salt loses water to form an amide... [Pg.860]

The A/-carboxyl group is lost duting the reaction, and no additional deprotection step is requited (104). Benzene reacts with A/-carboxyglyciae anhydride to give aminomethyl phenyl ketone however, it does not react with other A/-carboxy-a-amino acid anhydrides (105). [Pg.558]

This was transformed into the quaternary d-bromocamphorsulphonate, m.p. 265°, but no resolution has yet been effected. The lactam of 3-carboxyhexahydrocarbazole-1 ll-)3 8 -dipropionic acid (XXIV, with a carboxyl group at C ), CigH jO N, rn.p. 257-8°, has also been prepared. The same authors, with Holmes, have synthesised the lactam of 11-ethylhexahydrocarbazole-l-)3-propionic acid, Ci,H3iON, m.p. 106-8-107-5°, of which (XXrV) is a carboxy-derivative. [Pg.581]
