Cover Feature: Computational and Experimental Evidence of Two Competing Thermal Electrocyclization Pathways for Vinylheptafulvene (Chem. Asian J. 8/2019)

A potential energy surface (PES) with two pathways that result in different diastereoisomers is shown in the cover feature. The Woodward–Hoffmann (WH) allowed path and the disallowed path are shown in blue and in red, respectively. The two pathways are shown to have comparable transition state energies. The PES is imposed on a picture of New Zealand′s beautiful nature that was taken by Prof. Kjaergaard during the time he lived in New Zealand. More information on the research study can be found in the Full Paper by Henrik Kjaergaard et al. on page 1111 in Issue 8, 2019 (DOI: 10.1002/asia.201800437).
