functionalized 1-naphthols using alkynes and 1,3-dicarbonyl compounds by (4 + 2) annulation of C-centered radical. Electrolysis was conducted with Cp2Fe as redox catalyst, thereby eliminating the use of oxidants and transition-metal catalysts. The synthesized 1-naphthol compounds showed good antitumor activity in vitro, and further studies indicated that compound 3bl induced tumor cell apoptosis.
在电化学条件下以C为中心的自由基环化是构建环状结构的可行策略。本文报道的是使用炔烃和1,3-二羰基化合物通过C-中心自由基的(4 + 2)环化电化学合成高度官能化的1-萘酚。用Cp2Fe作为氧化还原催化剂进行电解,从而消除了氧化剂和过渡金属催化剂的使用。合成的1-萘酚化合物在体外显示出良好的抗肿瘤活性,进一步的研究表明,化合物3b1诱导肿瘤细胞凋亡。
