titleOfInvention | Regiospecific process to make cis-1-amino-2-alkanols |
abstract | A regioselective process for synthesizing any enantiomer of cis-1-amino-2-indanol or mixture of said enantiomers, said process substantially retaining the stereochemical integrity of the carbon-oxygen bond at C-2 in the indene oxide starting material, wherein the process comprises the steps of: (a) providing one equivalent of indene oxide dissolved in a solvent and, optionally, a co-solvent, said solvent selected from an alkyl nitrile or aryl nitrile; (b) mixing thereto about two equivalents of an acid, said acid selected from a strong protic acid or a Lewis acid or an organic acid, and maintaining thereafter the temperature of the resulting mixture between about -70 DEG C and about +30 DEG C for a time period of between about 0.25 hour and about 6.0 hours; (c) adding excess water to effect hydrolysis, and stirring for a time period of between about 0.5 hour and about 8.0 hours, at a temperature of between about 25 DEG C and about 100 DEG C, to give the corresponding enantiomer of cis-1-amino-2-indanol, or mixture of said enantiomers. |
