dehydrogenative coupling reaction of glycine esters with β-naphthols has been achieved via the synergistic combination of photoredox catalysis and Lewis acid catalysis. A wide range of glycine esters and β-naphthols are suitable substrates for this reaction. A variety of 1,3-benzoxazines were obtained in good yields with excellent diastereoselectivities under mild reaction conditions. Moreover, this
通过光氧化还原催化和路易斯酸催化的协同作用,实现了甘氨酸酯与β-萘酚的直接好氧氧化脱氢偶联反应。各种各样的甘氨酸酯和β-萘酚是该反应的合适底物。在温和的反应条件下,以良好的非对映选择性高收率获得了多种1,3-苯并恶嗪。而且,该协议可以以克为单位执行,而不会造成很大的活动损失。
