A facile, convenient and high yielding synthesis of a series of novel 5-(3′-indolyl)-2-(substituted)-1,3,4-oxadiazoles from readily available starting materials has been described. The key step of this protocol is oxidative cyclization of N-acylhydrazones 1 using [bis(trifluoroacetoxy)iodo]benzene under solvent-free condition. The 5-(3′-indolyl)-2-(substituted)-1,3,4-oxadiazoles were screened for their
已经描述了从容易获得的起始原料容易,方便且高产率地合成一系列新颖的5-(3'-吲哚基)-2-(取代的)-1,3,4-恶二唑。该协议的关键步骤是在无溶剂条件下使用[双(三氟乙酰氧基)碘]苯对N-酰基hydr 1进行氧化环化。筛选了5-(3'-吲哚基)-2-(取代)-1,3,4-恶二唑类化合物对各种人类癌细胞系的体外抗癌活性。化合物3C,3D和3J显示出强的细胞毒性(IC 50〜1μM)和选择性针对人肿瘤细胞株。
