Verfahren zur Herstellung von Isoprenderivaten |
摘要 |
<p>A process is described for the preparation of isoprene derivatives of the general formula <IMAGE> in which the asymmetric centres independently of one another can have the (R)- or (S)-configuration, R being a radical of the formulae <IMAGE> R<1> being lower alkyl, or both R<1>'s together being ethylene or propylene, and n being the number 0, 1 or 2, in which a compound of the general formula <IMAGE> which has the (E) or (Z) form and in which R, n and an asymmetric centre which may be present have the abovementioned meaning, is subjected to asymmetric hydrogenation using a ruthenium complex of an optically active atropisomeric diphosphine.</p> |
