In compound-centered design, which statement about isolation is accurate?

• A. Isolation of natural products is always straightforward.
• B. Synthesis is always easier than isolation.
• C. Natural products are always abundant.
• D. Natural products may be easier to isolate than to synthesize.

Answer: (D)

In compound-centered design, the challenge of isolation versus synthesis often balances toward isolation being easier. The natural product is produced by the organism through biosynthetic pathways, so you can exploit straightforward extraction and separation techniques—think solvent extraction, partitioning, and chromatography—to separate the target compound from a complex mixture. This can yield usable material without having to piece together every bond and stereocenter from scratch. In contrast, total synthesis requires designing a multi-step route, managing stereochemistry, protecting groups, and often dealing with very low overall yields, which makes synthesis substantially more demanding than isolation in many cases. So the statement that natural products may be easier to isolate than to synthesize best captures this practical reality. The other options aren’t universally true: isolation isn’t always straightforward, synthesis isn’t always easier, and natural products aren’t always abundant.
