The electrochemical and chemical oxidations of 4-(3,4-dimethoxybenzyl)-6,7-dimethoxy-2-methyl-1,4-dihydro-3(2H)-isoquinolone fail to yield an intramolecularly coupled product, yet the corresponding lactone 4-(3,4-dimethoxybenzyl)-6,7-dimethoxyisochromanone affords both intramolecularly and intermolecularly coupled structures. Some aspects of the mechanism of these reactions are considered and attempts
4-(3,4-二甲氧基苄基)-6,7-二甲氧基-2-甲基-1,4-二氢-3(2 H)-异喹诺酮的电化学和化学氧化未能产生分子内偶联的产物内酯4-(3,4-二甲氧基苄基)-6,7-二甲氧基异苯并二氢吡喃酮提供分子内和分子间偶联的结构。考虑了这些反应机理的某些方面,并描述了合成异吗啡酮和双烯酮的尝试。
