摘要:
二维 [ 1 H, 15 N] NMR 研究表明,在单官能团 DNA 加合物模型 [Pt([ 15 N 3 ]dien)(5â²-GMP-N 7 )] 2+ [5â²-GMP = 鸟苷酸 5â²-monophosphate, dien = 1、5-二氨基-3-氮杂戊烷(通过甘氨酸的新合成法制备)],配位 5â²-GMP的 5â²-磷酸基和 N 1 H 的去质子化促进了涉及 PtâNH 质子的立体特异性氢键相互作用。

(15N)Dien and (15N)en have been synthesized from 15 N-glycine via amidation and reduction reactions with trityl as amino-protective group. The method is economic, mild and easy to handle.
