Process for the stereoselective preparation of a hetero-bicyclic alcohol enantiomer

The invention relates to a method for the stereoselective preparation of a hetero-bicyclic alcohol enantiomer, characterized in that a substantially pure enantiomer of the general formula STR1 is prepared from a compound of the general formula STR2 wherein the variable are as defined as in claim 1. The method comprises the following successive reaction steps: (i) reaction with a substantially enantiomerically pure compound of the general formula STR3 wherein Z, R3 and R4 are defined as in claim 1; (ii) subjection of the compound formed to a deprotection/ring-closure reaction; (iii) optionally deprotection of the hydroxy group of the ring-closed product. The invention further relates to enantiomerically pure intermediates, the preparation of these intermediates and the preparation of a starting compound.

Synthesis of Some Novel Potent and Selective Catechol O-Methyltransferase Inhibitors

A series of disubstituted catechol derivatives was synthesized and tested as potential COMT inhibitors.The most active compounds were more than 1000 times more potent (IC 50 = 3-6 nM) in vitro than the known COMT inhibitor, 3',4'-dihydroxy-2-methylpropiop
