- Abstract
The front cover picture, provided by Yanlong Gu and co ‐ workers, describes a class of versatile benzannulation reagents, 2 ‐ alkoxy ‐ 2,3 ‐ dihydrofurans that can be obtained from readily available substrates through a simple synthetic operation. Indoles, carbazoles, naphthalenes, benzofurans, and benzothiophenes can be synthesized via the [4+2] annulation of 2 ‐ butoxy ‐ 2,3 ‐ dihydrofuran with various electron ‐ rich heterocycles or arenes in the presence of Lewis acid or Brønsted acid catalysts. Details can be found in the communication on pages 2260 – 2266 (C. Liu, W. Huang, M. Wang, B. Pan, Y. Gu, Adv. Synth. Catal. 2016, 358, 2260 – 2266; DOI: 10.1002/adsc.201600185).
