🔬 Amphidinolide A (from Amphidinium sp.) ✨ Consider this: even though we can split the atom, Amphidinolide A still humbles the world’s top chemists. Nature assembles this intricate macrocycle in seconds, yet we have spent decades laboring to isolate just a milligram in the laboratory. ✓ 🧩 1. The molecule contains a 28‑member macrocyclic lactone with multiple fused tetrahydropyran rings and a cyclohexene, forming a highly strained polyether architecture. ✓ 📐 2. It possesses 18 stereogenic centers distributed across the macrocycle and side chain, demanding absolute stereocontrol at each step. ✓ 📉 3. Total synthesis exceeds 90 linear steps, delivering overall yield below 0.001%, making gram‑scale production impractical. 🟢 Do you think AI and automation will finally crack these seemingly impossible architectures? #SyntheticChemistry #NaturalProducts #AmphidinolideA #ChemicalComplexity #AIinChemistry
