π-system. This carbonate reacted fast enough to avoid scrambling and formation of symmetric bisallyl tetronicacids. The 3-allyl-3-penta-2,4-dienyltetronic acid thus obtained is a key intermediate en route to the natural spirolactone bakkenolide A. allylation - regioselectivity - palladium -tetronicacid- Schlosser-Wittig reaction
