centrally acting dopamine (DA) agonists acting on both pre- and postsynaptic DA receptors. The compounds resolved are 5- and 7-hydroxy-2-(di-n-propylamino)tetralin and cis- and trans-7-hydroxy-4-n-propyl-1,2,3,4,4a,5,6,10b-octahydrobenzo [f]quinoline. By the superimposition of the structures of the more active enantiomers of these compounds with those of known dopaminergic agonists, apomorphine and ergolines

Rotigotine is a launched drug for the treatment of Parkinson’s disease and restless legs syndrome. The key steps of an alternative route for the synthesis of rotigotine have been demonstrated. Formation of a prochiral enamide, asymmetric hydrogenation of the enamide with high enantioselectivity, and reduction of the resulting amide to an amine have been proved to work successfully.

Catalyst-controlled asymmetric ring opening of a racemic oxabicyclic alkene leads to two readily separable regioisomeric products both in excellent ee. A cationic Rh catalyst, with added NH4BF4 to modulate reactivity, was required to obtain synthetically useful yields. The utility of each substituted aminotetralin product has been demonstrated by their conversion to different biologically relevant
