Cover Picture: Formation of Phenyliodonio‐Substituted Spirofurooxindole Trifluoroacetates from N‐Substituted 3‐Oxopentanediamides via Phenyliodine Bis(trifluoroacetate)‐Mediated Oxidative Cascade Reactions (Adv. Synth. Catal. 15/2017)

The inside cover picture, provided by Yunfei Du and co-workers, illustrates the reaction of N-substituted 3-oxopentanediamides with phenyliodine bis(trifluoroacetate) (PIFA), which was found to give a novel class of phenyliodonio spirooxindole compounds under metal-free conditions. The reaction is postulated to undergo a cascade process involving an oxidative C–O bond formation, an oxidative C–C bond formation and a final iodination step. Details can be found in the communication on pages 2542–2548 (B. Hu, Y. Cao, B. Zhang. D. Zhang-Negrerie, Y. Du, Adv. Synth. Catal 2017, 359, 2542–2548; DOI: 10.1002/adsc.201700075).
