The syntheses of the polyketide and terpenoid fragments of actinoranone are reported in a concise fashion, relying on catalytic methods. Minimization on the use of protecting groups and redox reactions allowed the synthesis of the carbon backbone of actinoranone in 20 steps (11 steps for LLS). The asymmetric synthesis of labda-7,13-(E)-dien-15-ol is also disclosed.
