Studies Concerned with the Structure and Synthesis of the Anti‐viral Tropolone Glycoside Liriosmaside A

ChemistryOpen, EarlyView.
The core of the anti‐viral troponoid natural product liriosmaside A lacking the 3‐hydroxy‐3‐methylglutaric acid (HMGA) side‐chain at C6′ has been prepared. The early steps involved the gem‐dibromocyclopropane‐mediated ring‐expansion of a readily‐obtained Robinson annulation product.
