Multicomponent Coupling Approach to (±)-Frondosin B and a Ring-Expanded Analogue

Kerr, Daniel J.,Willis, Anthony C.,Flynn, Bernard L.

, p. 457 - 460 (2007/10/03)

(Equation presented) A recently discovered multicomponent coupling reaction is used to give direct access to a late intermediate in the synthesis of frondosin B. This intermediate can also be efficiently converted to a ring-expanded analogue of frondosin
