Building blocks from abcr – information, facts, application areas

The pharmaceutical industry has especially used building blocks intensively since the 1990s as these are used for researching pharma-active agents. Building blocks often function like “libraries”, i.e. as a carefully chosen selection of a few hundred to thousand building blocks for screening new active agents.

Building blocks are synthesis building blocks, which are used to produce organic molecules. Building blocks most often have one or multiple functional groups. Moreover, they are linked to other synthesis building blocks: Heterocyclic core structures such as pyridine, pyrrolidine or thiophene can be substituted with functional groups such as alcohols, aldehydes, carbonic acid, amines, amides, sulphonic acids, boronic acids, anhydrides, esters, nitriles, nitro compounds, diazo compounds, cyanates, isocyanates, alkenes, alkines or fluorine-containing groups.

Methods from combinatorial chemistry allow for the parallel synthesis of a multitude of similarly structured molecules. Suitable reaction conditions can cause building blocks to react in a targeted manner with high yields. The palladium-catalysed cross-coupling of Heck, Negishi and Suzuki is to be mentioned here as an example. In 2010, all three research groups received the Nobel Prize in Chemistry.
