Syntheses of (±)‐Rhodonoid D, (±)‐Rhodonoid G, and (±)‐Ranhuadujuanine B

Divergent total syntheses of (±)‐rhodonoids D, G, and (±)‐ranhuadujuanine B are reported, utilizing a chromone efficiently constructed via the Kabbe condensation. The strategy features two key transformations: a synergistic aldol reaction and intramolecular Michael addition to precisely assemble the distinctive 6/6/5/5 fused ring system with high regioselectivity and stereospecificity, and an innovative one‐pot hemiketalization‐reduction cascade for efficient formation of the tetrahydrofuran ring.
