Synthesis of2H,13C-Labelled 2′-Deoxynucleosides and Their Site Specific Incorporation into Oligo-DNA for Structural Studies via Relaxation Time Measurements
摘要:
We have recently shown(1) the usefulness of H-2,C-13-labelled 2'-deoxynucleoside building blocks for structural studies via relaxation time measurements. The synthesis of phosphoramidite blocks 11 and 12 for their site-specific incorporation (indicated by underlines) into the d(5')((1)C(2)G(3)(A) under bar(4)(T) under bar(5)(T) under bar(6)(A) under bar(7)(A) under bar(8)(T) under bar(9)C(10)G)(2)(3') is briefly described for studying the T-1 and T-1 rho relaxations of H-2 and C-13 at specific deuterated carbons in a large molecule.
