Definitions
- the present invention relates to a process for the preparation of substituted amino-indane derivatives by cyclization.
- 4-amino-indanes and corresponding derivatives are important intermediates for the preparation of bioactive compounds, which can be used especially for controlling harmful microorganisms in crop protection.
- pyrazole-indanylcarboxamides are known to have fungicidal activity (e.g., WO 1992/12970, WO 2012/065947, Org. Chem. 1995, 60, 1626 and WO 2012/084812).
- Indanes without amino functionality on aromatics can be prepared by Friedel-Crafts cyclizations according to established methods in classical organic chemistry. For this purpose, aromatics having hydroxyalkyl or alkene side chains by adding BrOnsted acids such as HCl, HBr, HF, H2SO4, H3PO4, KHSO4, AcOH, p-toluenesulfonic acid, polyphosphoric acid or Lewis acids such as AICI 3 , BF 3 , AgOTf converted to the corresponding indanes.
- BrOnsted acids such as HCl, HBr, HF, H2SO4, H3PO4, KHSO4, AcOH, p-toluenesulfonic acid, polyphosphoric acid or Lewis acids such as AICI 3 , BF 3 , AgOTf converted to the corresponding indanes.
- substituted 4-amino-indan derivatives obtainable by this desired process should preferably be obtained in high yield and high purity.
- the intended method should enable the desired target compounds to be obtained without the need for complex purification methods such as column chromatography.
- substituted 4-amino-indane derivatives can be prepared by a sulfonic acid-mediated cyclization reaction.
- Preferred sulfonic acids are methanesulfonic acid or trifluoromethanesulfonic acid and particularly preferably trifluoromethanesulfonic acid. This is all the more surprising because so far no such reaction has been described and the skilled person would have expected that it would come by the action of these very strong acids to a decomposition of the starting material and / or the resulting products. In addition, it was to be assumed that - as with the use of other Br ⁇ nsted or Lewis acids - there would be no successful cyclization.
