The inside cover picture, provided by Lutz Ackermann and co-workers, demonstrates the design of the novel palladium complex derived from a secondary bisdiamantyl phosphine oxide preligand that enables the facile activation of challenging C−H bonds of oxazolines without the need of directing groups. The user-friendly palladium catalyst also proved effective for synthetically useful heterocyclic electrophiles, which sets the stage for the step-economical synthesis of pybox ligands under racemization-free reaction conditions. Details of this study can be found in the full paper on pages 3137–3141 (D. Ghorai, V. Müller, H. Keil, D. Stalke, G. Zanoni, B. A. Tkachenko, P. R. Schreiner, L. Ackermann, Adv. Synth. Catal. 2017, 359, 3137–3141; DOI: 10.1002/adsc.201700663).
