Holmes et al. [33] reported the solution and polymer-supported synthesis of 4-thiazolidinones 3 and 4-metathiazanones 4 derived from amino acids. A three-component condensation of an amino acid ester or a resin-bound amino acid (glycine, alanine, j8-alanihe, phenylalanine, and valine), an aldehyde (benzaldehyde, o-tolualdehyde, m-tolualdehyde, p-tolualdehyde and 3-pyridine carboxaldehyde), and an a-mercapto carboxylic acid led to the formation of five- and six-membered heterocycles (Fig. 3b). 

Coenzyme A (for acetylation) contains four structural units ADP, pantoic acid (a vitamin), 3-alanine, and (3-mercapto ethylamine (cysteamine) (Scheme 7.3.7). 

The stability constants of uranyl amino- and mercapto-acid complexes have been determined. Among the acids investigated were cysteine, methionine, P-alanine, anthranilic acid, serine, threonine, and JV-ac tylglycine. Stability constants of a series of chloro-, bromo-, iodo-, and nitro-substituted salicylic acid and of o-pyrocatechinic, y-resorcylic, and gentisic acids complexes of UOj" have been measured 1 1 and 1 2 species were identified. It was observed that there was a distinct dependence of stability constant on the charge of the central metal atom in UO ", NpO, and Pu " tropolonato complexes. ...
