Title: Cover Picture: An Enantioselective Cascade Cyclopropanation Reaction Catalyzed by Rhodium(I): Asymmetric Synthesis of Vinylcyclopropanes (Adv. Synth. Catal. 22/2016)
Abstract: The inside cover picture, provided by Òscar Torres, Anna Roglans and Anna Pla-Quintana, illustrates the cascade reaction of N-tosylhydrazone-yne-ene substrates to enantioselectively afford vinylcyclopropanes under rhodium catalysis. The rhodium carbene formed under base-free conditions from the tosylhydrazone, undergoes a carbene/alkyne metathesis that generates a vinylcarbene, which enantioselectively cyclopropanates the tethered alkene. Details can be found in the communication on pages 3512–3516 (Ò. Torres, A. Roglans, A. Pla-Quintana, Adv. Synth. Catal. 2016, 358, 3512–3516; DOI 10.1002/adsc.201600789).
