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 oxidativecyclization 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

pro-apoptotic Bcl-2 inhibitory anticancer agents based on our previously reported hit compounds. Synthesis of the target 1,3,4-oxadiazoles was readily accomplished through a cyclization reaction of indole carboxylic acid hydrazide 2 with substituted carboxylic acid derivatives 3a–m in the presence of phosphorus oxychloride. New compounds 4a–m showed a range of IC50 values concentrated in the low micromolar range
