Synthetic Production of Potential Pharmaceuticals Dramatically Simplified by Scripps Research Team

Chemists are currently able to synthetically produce almost any compound, but they must typically resort to expensive, complex processes that can require dozens of individual steps. Such natural product syntheses have traditionally relied on the ubiquitous use of “protecting groups,” which are extra compounds chemists use to shield reactive portions of a molecule during specific stages of a synthesis scheme. The protecting groups are eventually cleaved chemically to expose the reactive portion during later chemical reactions to complete a product's synthesis. Each protecting group used adds at least two steps to a synthesis, and the groups themselves have reactivity of their own that must be controlled to prevent adverse reactions.
