Abstract:
Thapsigargin (3) is a potent inhibitor of the SERCA-pump protein, with potential for application in a variety of medicinal areas. The efficient and scalable syntheses of thapsigargin (3) and nortrilobolide (2) have been disclosed previously. To demonstrate the modularity of the previous routes, three natural products (compounds 6, 13, 15) and four analogs (compounds 17-20) have been divergently prepared from a common building block featuring varied acyl chains at the C2, C3, and C8 positions. Biological tests revealed that all of the compounds prepared displayed promising activity profiles.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
