Synthesis of new aminoacyl-adenylate analogs having an N-acyl phosphoramidate linkage
摘要:
New aminoacyl-adenylate analogs (aa-AMPNs), in which the oxygen atom of the mixed anhydride bond of aminoacyl-adenylates is replaced by an NH group, were synthesized by the reaction of an adenosine 5'-phosphoramidite derivative with appropriately protected amino acid amides. Among various reagents studied for activation of the 5'-phosphoramidite derivative, 5-(4-nitrophenyl)-1H-tetrazole was found to give N-acyl phosphoramidate derivatives in good yields.

This paper describes the design and synthesis of a new type of aminoacyl-adenylate analogue (aa-AMPN) having an N-acyl phosphoramidate linkage where the oxygen atom of the mixed anhydride bond of aminoacyl-adenylate (aa-AMP) is replaced by an amino group. This new type of aa-AMP analogue is expected to be useful as material for studies on the recognition mechanism of the aminoacylation of tRNA and
