Dihydrogen TctrakisicarboxymethylthioIatoltellurateCII)1 Sodium tellurite and mercaptoacetic acid are combined in a 1 8 molar ratio in 1 normal sulfuric acid. The resultant mixture is extracted with ethyl acetate, the organic phase is shaken repeatedly with aqueous cadmium chloride solution to remove excess mercaptoacetic acid, the organic phase is dried with sodium sulfate, the mixture is filtered, and the solvent is evaporated at 0° under reduced pressure to leave yellow crystals of the product. 

The ligands showing this behaviour are acetic acid, mercaptoacetic acid, methoxyacetic acid, acetylacetone, dipicolinic acid and A -(2-hydroxyethyl)ethylenediamine A,A,A -triacetic acid. 

Reagent Trichloroacetic Acid-Mercaptoacetic Acid Reagent. Dissolve 100 g of hicbloroacetic acid in 500 ml of water, add 30 miofmercap to acetic acid and 166 ml of hydrochloric acid, allow die mixture to cool to room temperature and dilute to 1000 ml widi water. The reagent should be stored in an amber bottle.

Pyrimido[5,4-6][l, 4]thiazines are synthesized by reaction of 6-amino-5-chloro-uracils with mercaptoacetic acid in alkaline solution, followed by dehydration in acetic anhydride (62JA1904). Chlorosulfonation and subsequent amination of 6-aminouracil give the corresponding 5-sulfonamides, which are cyclized to pyrimido[4,5-c][ 1,2,4]thiadiazines on heating in triethyl orthoformate (63JOC1994) (Scheme 61). 

In addition to four component condensation, several other applications of chiral primary ferrocenylalkyl amines have been published. Thus, an asymmetric synthesis of alanine was developed (Fig. 4-3la), which forms an imine from 1-ferrocenylethyl amine and pyruvic acid, followed by catalytic reduction (Pd/C) to the amine. Cleavage of the auxiliary occurs readily by 2-mercaptoacetic acid, giving alanine in 61% ee and allowing for recycling of the chiral auxiliary from the sulfur derivative by the HgClj technique [165]. Enantioselective reduction of imines is not limited to pyruvic acid, but has recently also been applied to the imine with acetophenone, although the diastereoisomeric ferrocenylalkyl derivatives of phenylethylamine were obtained only in a ratio of about 2 1 (Fig. 4-31 b). The enantioselective addition of methyl lithium to the imine with benzaldehyde was of the same low selectivity [57]. Recycling of the chiral auxiliary was possible by treatment of the secondary amines with acetic acid/formaldehyde mixture that cleaved the phenylethylamine from the cation and substituted it for acetate. 

The Npys group can be cleaved reductively with BU3P, H2O or mercaptoetha-nol. It has also been cleaved with 2-mercaptopyridine, 2-mercaptomethylimidazole, or 2-mercaptoacetic acid in methanol/acetic acid. Selective cleavage of the 0-Npys bond over the 5-Npys bond can be achieved with the aromatic thiols. This group...

Thiazolidones are another class of heterocycles that attract much attention because of their wide ranging biological activity [106], They are usually synthesized by three-component condensation of a primary amine, an aldehyde, and mercapto-acetic acid with removal, by azeotropic distillation, of the water formed [107]. The reaction is believed to proceed via imine formation then attack of sulfur on the imine carbon. Finally, an intramolecular cyclization with concomitant elimination of water occurs, generating the desired product. The general applicability of the reaction is limited, however, because it requires prolonged heating with continuous removal of water. To circumvent these difficulties and to speed up the synthesis, Miller et al. developed a microwave-accelerated three-component reaction for the synthesis of 4-thiazolidinones 63 [108]. In this one-pot procedure, a primary amine, an aldehyde, and mercaptoacetic acid were condensed in ethanol under MW conditions for 30 min at 120 °C (Scheme 17.44). The desired 4-thiazolidinones 63 were obtained in 55-91% yield.
