Definitions
- the present invention relates to geminally substituted amines.
- the present invention relates to amines substituted with aryl group-containing substituents, combinatorial libraries of such amines and special uses of these amines as intermediates in combinatorial drug synthesis or as drugs in pharmaceuticals.
- a prerequisite for the combinatorial synthesis of active substance libraries is the accessibility of suitable starting compounds which either already contain a biologically active structural element or form this through combinatorial synthesis. Furthermore, the starting compounds must be suitable to provide as many of the reaction products as possible by law in the same possible yield in order to reduce the influence of the concentration of the individual compounds during screening and to create a combinatorial library that is as complete as possible.
- the object of the invention is therefore to provide new compounds which contain a special biologically active structural element and which can be used individually or as a library in the combinatorial synthesis of active substances.
- This object is achieved by providing an amine of the following formula (I) as a pure substance or in a substance library in a mixture with several different amines of the formula (I). It has been found that, surprisingly, the geminal substitution of a preferably tertiary amine can not only provide biological activity, but at the same time its preparation also has advantageous properties in combinatorial active ingredient synthesis. A process is also proposed in which a large number of amines of the general formula (I) can be prepared as a substance library.
