Definitions
- the present invention relates to a process for the preparation of cyclopropylamines from carboxamides and olefins.
- cyclopropylamines are of the greatest importance. A number of aminocyclopropane carboxylic acids occur naturally. Many cyclopropylamines have recently been used as building blocks for new drugs (see Pharmacology and Toxicology, Academicsverlag Mannheim, 1993, p. 655). Interesting are e.g.
- Cyclopropanamino acids as enzyme inhibitors and for other applications in pharmacology and crop protection.
- the incorporation of cyclopropylamines in key positions of peptide chains can be used to specifically change their secondary and tertiary structure.
- cyclopropyl groups By incorporating cyclopropyl groups, latent instability is created in the peptide in question at the center, which can react with electrophilic or nucleophilic centers of receptors and enzymes (J. Org. Chem. 54, 5866 (1989)).
- the conformingly determined cyclopropane analog 2,3-methanovalin was produced (op. cit.).
- the conformally determined cyclopropane analogues for studying the receptor geometry and the mechanism of action can be synthesized, in each case as ice or trans diastereomers (J. Med. Chem. J_7, 1100 (1974) ; 18, 1027 (1975); 22, 458 (1979); 25, 526 (1982); 26, 817 (1983) and Chem. Pharm. Bull. 27, 1893 (1979)).
