Last month I posted a scheme from a paper by Jonathan H. George et al at the University of Adelaide describing a biomimetic total synthesis of the Rhododendron meroterpenoids rubiginosins A and G and asked if you could identify reagents or intermediates B, D, E and H. Below are the answers! You can read more here in the full reference: J. George et al, Org. Lett. 2021, 23, 578–582, DOI: 10.1021/acs.orglett.0c04117
Hope you enjoyed the challenge- stay tuned for Identify the Reagent 2!
