Die palladiumkatalysierte Amidocarbonylierung — eine neue effiziente Synthese vonN-Acylaminosäuren

Catalysts for Cross-Coupling Reactions with Non-activated Alkyl Halides

Despite the problems inherent to metal-catalyzed cross-coupling reactions with alkyl halides, these reactions have become increasingly important during the last few years. Detailed mechanistic investigations have led to a variety of novel procedures for the selective cross-coupling of non-activated alkyl halides bearing beta hydrogen atoms with a variety of organometallic nucleophiles under mild reaction conditions. This Minireview highlights selected examples of metal-catalyzed coupling methods and is intended to encourage chemists to exploit the potential of these approaches in organic synthesis.

Catalysis as a key technology for the environmentally benign synthesis of amines and amino acids

The rhodium-catalyzed amination of aromatic olefins and the palladium-catalyzed amidocarbonylation of aldehydes are presented as new atom-efficient methods to yield biologically interesting amines and N-acyl amino acids.

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.
