bonded through a vinyl spacer in the yields range 40-71%. The presence of not-separable isomers of the naphthoquinone amino acids conjugates in the ¹H- and 13C-NMR spectra is explained by the existence of conformational isomers generated by hindered rotation of the substituent bonded to the quinone double bond. These new naphthoquinone amino acids conjugates were screened in vitro on normal and cancer cell
2-乙酰基和2-苯甲酰基-1,4-萘醌与(Z)-3-(羟甲基)氨基巴豆酸甲酯的反应通过正式的[3 + 3]过程进行,从而在63中得到相应的1,2-二氢苯并异喹啉喹啉%和72%的收率分别。2-酰基-1,4-萘醌与衍生自不同的1-和d-氨基酸甲基酯的烯胺酮的反应产生了通过乙烯基间隔基键合的相应的萘醌氨基酸共轭物,产率范围为40-71%。在1 H-和13 C-NMR光谱中萘醌氨基酸共轭物的不可分离的异构体的存在是由于存在由于与醌双键结合的取代基的旋转受阻而产生的构象异构体。
