Carboxylate esters react with 1,2-diaminoethanes to yield imidazolines, which upon consecutive reaction with acetic anhydride or tosyl chloride and methyl iodide give imidazolinium salts that serve as models of N5,N10-(CH+)-tetrahydrofolate (THF) coenzymes (7a,b and 18a,b).Reduction of the latter salts with sodium borohydride or reaction with anions (R-) give the corresponding 5,10--THF models.Mono- and bifunctional nucleophiles react with 18a,b to yield carbon-transfer products. 6-Alkylamino-1,3-dimethyluracils react with 1-tosyl-3,4,4-trimethylimidazolidine (the reduction product of 18b), in the presence of acetic acid, to form carbon-transfer products via a mechanism which bears close analogy to the mechanism of action of thymidylate synthetase.
