Herein we disclose the assembly of benzoxepines and coumarins from 2-alkenylphenol precursors using [Cp*RhCl2]2 as the precatalyst and alkynes or carbon monoxide as reacting partners. The preparation of benzoxepines and coumarins can be scaled up to 33 mmol using low catalyst loadings.
Synthesis of 8-aryl-substituted coumarins based on ring-closing metathesis and Suzuki-Miyaura coupling: Synthesis of a furyl coumarin natural product from Galipea panamensis
