In view of the anticancer activity of thiophene-2,5-dicar☐ylic acid, a series of derivatives of this acid were prepared. Starting from 2,5-dichloromethylthiophene, thiophene-2,5-dialdehyde, thiophene-2,5-dimethylenyl-thiouronium dichloride, 2,5-dimercaptomethylthiophene were prepared. 3,4-Dihydroxylthiophene, a thiophene isoster of catechol, was prepared by decar☐ylation of 2,5-dicar☐y-3,4-dihydroxythiophene
鉴于噻吩-2,5-二甲基二羧酸的抗癌活性,制备了该酸的一系列衍生物。从2,5-二氯甲基噻吩开始,制备噻吩-2,5-二醛,噻吩-2,5-二甲基烯基-硫脲鎓二氯化物,制备了2,5-二巯基甲基噻吩。3,4-二羟基噻吩,一种邻苯二酚的噻吩异构体,是通过将2,5-二甲基☐y-3,4-二羟基噻吩去甲酰基化而制得的。在所报道的化合物中,上述二硫代尿nium盐被证明对大鼠的吉田肉瘤具有很高的活性。
