trans-syn-Fused drimane meroterpenoids are unique natural products that arise from contra-thermodynamic polycyclizations of their polyene precursors. Herein we report the first total syntheses of four trans-syn-fused drimane meroterpenoids, namely polysin, N-acetyl-polyveoline, chrodrimanin C, and verruculide A, in 7–18 steps from sclareolide. The trans-syn-fused drimane unit is accessed through an
