摘要 采用氢谱(1H NMR)、碳谱(13C NMR)、梯度场氢氢化学位移相关谱(1H-1H COSY)、梯度场质子检测异核单量子化学位移相关谱(HSQC)、梯度场质子检测异核多重键化学位移相关谱(HMBC)等多种NMR分析方法,确证了8a-对甲氧苯基-4,5-双(对氯苯基)六氢嘧啶[4,5-d]并嘧啶-2,7(1H,3H)-二酮的结构,对它的1H和13C NMR谱信号进行了归属,为其结构鉴定提供了重要依据。 The molecular structure of 8a-( 4-methoxyphenyl)-4, 5-di ( 4-cholophenyl )-hexahydro- pyrimido[4,5-d]pyrimidine-2,7(1H,3H)-dione was elucidated by 1D NMR( ^1 H, ^13 C NMR) and 2D NMR techniques [ gradient homonuclear correlation spectroscopy ( ^1 H - ^1 H COSY), gradient heteronuclear single-quantum coherence (HSQC) and gradient heteronuclear multiple-bond coherence ( HM- BC) ]. The ^1 H and ^13 C NMR signals for 8 α- (4-methoxyphenyl) -4,5-di (4-cholophenyl) -hexahydropyrimido [ 4,5-d ] pyrimidine-2,7 (1 H, 3H)-dione were assigned. The data obtained could be used for its structure identification.
