Enantioselective construction of the tricyclic core of curcusones A-D a cross-electrophile coupling approach
Herein we report our recent progress toward the enantioselective total synthesis of the diterpenoid natural products curcusones A-D by means of complementary Stetter annulation or ring-closing metathesis (RCM) disconnections. Using the latter approach, we have achieved the concise construction of th...

| Summary: | Herein we report our recent progress toward the enantioselective total synthesis of the diterpenoid natural products curcusones A-D by means of complementary Stetter annulation or ring-closing metathesis (RCM) disconnections. Using the latter approach, we have achieved the concise construction of the

carbocyclic core embedded in each member of the curcusone family. Essential to this route is the use of a cross-electrophile coupling strategy, which has not previously been harnessed in the context of natural product synthesis.
Rapid assembly of the carbocyclic core of the curcusone family of natural products is achieved using reductive cross coupling and ring-closing metathesis disconnections. |
