Concept explainers
(a)
Interpretation: The tri-substituted
Concept Introduction:
Isomers of the organic molecules with the same type of molecular structures and different types of structures. On the basis of the structure and 3D arrangement of the molecules, the isomers can be classified as structural isomers and constitutional isomers.
The geometrical isomers are the isomers with different configurations around the double-bonded carbon atoms.
(b)
Interpretation: Total stereoisomers for pladienolide B are to be interpreted.
Concept Introduction: Isomers of the organic molecules with the same type of molecular structures and different types of structures. On the basis of the structure and 3D arrangement of the molecules, the isomers can be classified as structural isomers and constitutional isomers.

(c)
Interpretation: The enantiomers for pladienolide B are to be interpreted.
