Paragraph 0014; 0017; 0018, (2017/07/04)
The invention relates to a preparation method of optically pure (S)-1-aminoindane. The preparation method comprises steps as follows: 1-aminoindane is taken as a raw material, a solvent, Candida rugose lipase, an acyl donor L-(+)-O-acetyl mandelic acid and a racemization catalyst KT-02 are added to a high pressure kettle in proportion, hydrogen is introduced, all components react for a period of time, and then 1-aminoindane can be completely converted into an acetyl compound of (S)-1-aminoindane. A product is purified and subjected to acid hydrolysis and alkali free operation, (S)-1-aminoindane is obtained, and an ee value of a final product is larger than 99%. The preparation method has the characteristics that the operation is simple, the racemization catalyst is cheap and available, the raw material is completely utilized, the optical purity of the product is high and the like; the preparation method has great guidance and application value in the aspect of production and preparation of (S)-1-aminoindane.

Page/Page column 11, (2008/06/13)
Disclosed is a process for isolating from a reaction mixture a salt of a mono-propargylated aminoindan having the structure wherein R1 is H, hydroxyl, alkoxy or wherein Y is O or S; R2 and R3 is each, independently, C1-8 alkyl, C6-12 aryl, C6-12 aralkyl, each optionally halo substituted, or hydrogen; where the reaction mixture further comprises a solvent, a primary aminoindan having the structure wherein R1 is defined as above, and a tertiary aminoindan having the structure the process comprising d) adding an acid to the reaction mixture; e) crystallizing the mono-propargylated aminoindan under conditions suitable for the formation of a crystalline salt of the mono-propargylated aminoindan; and f) recovering the crystalline salt of the mono-propargylated aminoindan, wherein the process is performed without addition of an organic solvent. Also disclosed are the crystalline diastereomeric salts produced by the process and pharmaceutical compositions containing the salts.
