Abstract Reaction of C-ethyl esters of phosphonic- and phosphinic acidanalogues of glutamic and aspartic acids with ethyl orthoformate provides the mixtures of N-formylamino- and N-ethoxymethyleneimino-derivatives with nearly quantitative yields. Scope and limitations of this procedure were studied by means of GC/MS technique.

5-Deazafolate and 5-deazatetrahydrofolate (DATHF) analogues with the glutamic acid sidechain replaced by homocysteic acid (HCysA), 2-amino-4-phosphonobutanoic acid (APBA), and ornithine (Orn) were synthesized as part of a larger program directed toward inhibitors of folylpolyglutamatesynthetase (FPGS) as probes of the FPGS active site and as potential therapeutic agents. The tetrahydro compounds
