Gold‐Catalyzed Synthesis of Bicyclo[3.2.0]heptenes via a Formal [3+2]/[2+2]‐Annulation of Allylsilane with 4‐Methoxybut‐2‐yn‐1‐ols

Abstract This work reports the novel gold‐catalyzed [3+2]/[2+2]‐annulation of allylsilane with 4‐methoxybut‐2‐yn‐1‐ols that yields highly strained bicyclo[3.2.0]heptene products efficiently and stereoselectively.
