| titleOfInvention | Process for the preparation of the (-)-antipode of (E)-1-cyclohexyl-4, 4-dimethyl-3-hydroxy-2-(1,2,4-triazol-1-yl)-pent-1-ene |
| abstract | A process for the preparation of the (-)-antipode of (E)-1-cyclohexyl-4,4-dimethyl-3-hydroxy-2-(1,2,4-triazol-1-yl)-pent-1-ene of the formula ##STR1## which comprises reacting the (E)-isomer of 1-cyclohexyl-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-pent-1-en-3-one of the formula ##STR2## (a) with boron hydride in the presence of an optically active proline derivative of the formula ##STR3## in which, R 1 is alkyl, phenyl or benzyl, or n (b) with a complex borohydride in the presence of an acid addition salt of the optically active proline derivative, in the presence of a diluent at a temperature between about -70° C. and +60° C. The proline derivatives are also new and are produced from S-proline esters. The end product is a known plant growth regulant. |
