Domino reactions for library synthesis of small molecules in combinatorial chemistry

Domino reactions are highly efficient processes that allow the synthesis of complex molecules starting from simple substrates, in a straightforward fashion. The transformations are extremely useful for the design of small-molecule libraries by combinatorial chemistry if multicomponent domino reactions are employed. The reactions can be performed in solution, as well as on solid support, and give access to highly diverse molecules; in addition, their use in automated synthesis is possible.
