Synthesis of the DEF-Ring Spirocyclic Core of Cyclopamine

Strategic convergent synthesis en route to Veratrum steroidal alkaloids

“…42 Enlightened by the intriguing structures, the chemical synthesis of Veratrum steroidal alkaloids has thrived very recently. 43–49 Noteworthily, many of these newly reported syntheses commonly adopted convergent synthesis methods over the linear and/or semi-synthetic approach.…”
