A novel synthetic methodology of preparing tetrahydro-2(1H)-quinolones by Diels–Alder reactions between 2-methyl- and 2,3-dimethyl-1,3-butadienes and 1-arylsulfonyl-2(1H)-pyridones having an electron-withdrawing group at the 5-position is presented. Furthermore, the site-selectivity analyses based on MO calculations of the 5-substituted 2(1H)-pyridones acting as the dienophiles are described.
一种新的合成方法,该方法是通过2-甲基和2,3-二甲基-1,3-丁二烯与1-芳基磺酰基-2(1 H)-吡啶酮的Diels-Alder反应制备四氢-2(1 H)-喹诺酮给出了在5-位的吸电子基团。此外,描述了基于MO计算的用作双亲物的5-取代的2(1 H)-吡啶酮的位点选择性分析。
