Amido-acids

In sulfamation, also termed A/-sulfonation, compounds of the general stmcture R2NSO2H are formed as well as their corresponding salts, acid hahdes, and esters. The reagents are sulfamic acid (amido—sulfuric acid), SO —pyridine complex, SO —tertiary amine complexes, ahphatic amine—SO. adducts, and chlorine isocyanate—SO complexes (3).

In addition to the FAMA compounds described before, fatty acid amido polyethoxylates (CnH2n+i-C(0)N(H)(CH2-CH2-0)xH x > 1) were also applied as non-ionic surfactants contained in special formulations. These compounds are shown with their general structural formula in Fig. 2.9.34. Like FAMA, the molecules contain amino nitrogen and therefore could be easily ionised in the presence as well as absence of ammonium acetate by APCI or ESI in the positive mode in the form of [M + H]+ ions. Comparable spectra in both API techniques were observed under APCI or ESI ionisation.

Intramolecular cyclizations are not restricted to attack by a nucleophilic nitrogen (basic amino or acidic amido group). They can also be catalyzed by a nucleophilic oxygen as found in a carboxylate, phenolic, or alcoholic group. Illustration of the catalytic role of a carboxylate group can be found in hemiester prodrugs of phenol (taken as model compound) or paracetamol (Fig. 6 R = H or NHCOCH3, respectively). In addition to enzymatic hydrolysis, three mechanisms of chemical hydrolysis were seen, namely, acid-catalyzed, base-catalyzed, and an intramolecular nucleophilic attack. 

The same reactions are also applicable to substituted amines, like amido-carbonic acids, amido-sulphonic adds, halogen substituted amines, etc.
