Biosynthesis of Endiandric Acid B
Exercise: Interactive 3D Molecular Animation of the Endiandric Acid B Biosynthesis
The interactive 3D molecular model depicts the position in the biosynthesis of endiandric acid B just before the second electrocyclic ring closure.
Please start the animation of the second ring closure and look carefully at the mechanism. If necessary, repeat the animation. Then answer the question below.
Start of the animation of the second pericyclic ring closure.
