titleOfInvention | A method for the preparation of (2s, 3ar, 7as)-octahydro-1h-indole-2-carboxylic acid as key intermediate in the preparation of trandolapril by reacting a cyclohexyl aziridine with a dialkyl malonate |
abstract | A method for the synthesis of a compound of formula (I) as a mixture of enantiomers, formula (I) (wherein R1 is H or an acid protective group and H+A- indicates an optional acid with which the compound of formula (I) may form an ammonium salt) said method comprising; A) reacting a cyclohexyl aziridine with a dialkyl malonate, whereby to provide a trans-fused 3-alkylcarbonyl-octahydro-indol-2-one; B) decarbonylation at the 3-position, conversion of the ketone of the resulting trans-octahydro-indol-2-one to an optionally protected carboxylic acid group; and C) optionally removing any N-substitution if necessary. |
