氯化金(III)催化吡喃并[3,4- b ]吲哚-1(9 H)-酮的区域选择性合成及其对人宫颈腺癌的抗癌能力
摘要:
通过氯化金(III)催化3-乙炔基-吲哚-2-羧酸的环异构化,高度区域选择性地合成了吡喃并[3,4- b ]吲哚-1(9 H)-,得到了很好的收率。筛选这些化合物对人宫颈(HeLa)细胞系的体外细胞毒性。在十种化合物中,三种化合物(7d,7e和7j)显示出与标准药物顺铂相当的增殖抑制活性。发现化合物7d最有效,IC 50值为0.22μM。

A palladium(II)-catalyzed highly regioselective tandem reactions of o-alkynylbenzoates with methyl vinyl ketone for the synthesis of isocoumarins was developed. It is a convenient, mild and environmentally benign reaction with moderate to high yield. The reaction is initiated by the Pd(II) species and regenerate the Pd(II) species to complete the catalytic cycle without the necessity of a redox system
