Amide , amines from naming

Utilization of a,(3-unsaturated amides derived from the chiral amine, namely, camphor sultam, has been made by several groups to test the feasibility of [l,3]dipolar cycloaddition reactions with these chiral systems. This methodology has been applied to the synthesis of (35,4/ )ethyl-l-azabicyclo[2.2.1]heptane-3-carboxylate (see above for non-specific syntheses).433... [Pg.323]

Amides are named from the acid and amine from which they are prepared. The characteristic name ending is amide, replacing the -oic acid of the parent acid. For example ... [Pg.550]

In many cases, and particularly where aromatic amines are involved, we are more interested in the amine from which the amide is derived than in the acyl group. In these cases the substituted amide is named as an acyl derivative of the amine. For example ... [Pg.756]

The rules for naming amides derived from simple amines are as follows ... [Pg.325]

These data, as well as other information accumulated [6], are not in agreement with the most obvious interpretation of these phenomena, namely that partial ionization to (1, 5QH5) occurs on dissolution in apolar solvent. The NMR chemical shift behavior (i.e. effects are localized at C4/H4), lack of apparent rehybridization (a pyridinium salt has Jj3 = 180 Hz in contrast to the measured 149 Hz), and absence of cross-over all indicate that a pyridinium thiolate (1, SR) is not formed. A clue to the cause of these unusual effects is found in the observation that Dialkyl substituted amides derived from diethyl amine or proline otherwise analogous in structure to (2a) ionize immediately to pyridinium thiolates in CD3OD. No intermediate is observed. The spectra are fully consistent with pyridinium ions [6]. It is concluded that an amide proton is necessary for formation of the intermediate species. [Pg.225]

Hofmann degradation A method of preparing primary amines from acid amides. The amide is refluxed with aqueous sodium hydroxide and bromine RCONH2 + NaOH + Br2 RCONHBr + NaBr + H2O RCONHBr + OH- RCON-Br + H2O RCON-Br -> R-N = C = O + Br RNCO + 20H- RNH2 + C02 -The reaction is a degradation in the sense that a carbon atom is removed from the amide chain. It is named for the German chemist August Wilhelm von Hofmann. [Pg.112]

Two new sections on the protection for indoles, imidazoles, and pyrroles, and protection for the amide — NH are included. They are separated from the regular amines because their chemical properties are sufficienth different to affect the chemistry of protection and deprotection. The Reactivity Charts in Chapter 8 are identical to those in the first edition. The chart number appears beside the name of each protective group when it is first discussed. [Pg.475]

The ending caine stems from cocaine, the first clinically employed local anaesthetic. Procaine and tetracaine are ester-linked substances, the others are amides. Amide bonded local anaesthetics usually contain two i s in their name, ester-bonded only one. In the structure drawings, the lipophilic portion of the molecule is depicted at the left, the amine at the right. The asterisk marks the chiral centre of the stereoisomeric drugs. Lipid solubility is given as the logarithm of the water octanol partition coefficient, log(P). [Pg.702]

The choice of these derivatives, namely, those formed from amines of moderate strength, appears to be the best compromise for the synthesis to be effective. Although the susceptibility of phosphor-amidates to attack by nucleophiles increases with enhancement of the basic strength of the parent amine,279 280 the reverse trend is observed for the yields of nucleoside 5 -phosphoramidates when they are prepared from nucleoside 5 -phosphates by condensation with the appropriate amines through the action of N,N -dicyclohexylcarbodi-imide.279... [Pg.347]

Not listed and therefore not permitted are substances from chemical groups like pyrazines, pyridines, amines, amides, or aliphatic lower alcohols, aldehydes and hydrocarbons (C5 and lower) if not mentioned by individual name [17]. [Pg.22]

The condensation of a carboxylic acid with ammonia or an amine yields an amide. The amide in Table 15-1 resulted from the condensation of propanoic acid with ammonia. The example in the preceding section involved the condensation of acetic acid with a primary amine. A very important class of biochemical molecules are the amino acids, which join to form protein molecules by the condensation of the amine group of one molecule to the acid group of the next. The amide linkage in this case has the special name peptide. [Pg.240]
