Determination of the stereochemistry of organic compounds has been a problem that the scientific community has been giving solution to over the years. Different methods have emerged, such as X-ray Diffraction or different types of Nuclear Magnetic Resonance (NMR). However, it just has been discovered that the method used in the determination of the absolute configuration of the α-acids derived from hops used in the manufacture of bitter beers, was not the appropriate.

Organic synthesis has gone through many changes over the past few years, new concepts and reactions have been incorporated into the tools available for the synthesis. In 2011 the synthesis of Aspidophylline A, an alkaloid furoindoline, was reported. This synthesisis of great importance because it validates the interrupted Fischer indolization.
