| Abstrakt: |
The reaction of 2-aminoindole with a,ß-unsaturated aldehydes and ketones leads to a-carbolines, the ß-carbon atom of the oxo compound attacking C3 of the indole. In a number of cases, reactions with bifunctional derivatives take place with the cleavage of a carbon-carbon bond and the formation of the pentacyclic system of indolo[2,3-b]-a-carboline. The same substances are obtained from 2-amino-3-(arylmethylene)indoles and 3-(arylmethylene)-oxindoles. The replacement of one molecule of 2-aminoindole by other acceptors did not lead to the formation of unsymmetrical structures. |
