| abstract |
The present invention relates to stereospecific processes for the preparation of the 3-substituted furo [3,4-c] pyridine enantiomers of formula I, wherein R3, R4 and R6 represent various substituents, comprising the following steps: oxidation of d a racemic derivative of pyridine of formula II, followed by reduction of the ketone obtained by a reducing agent, stereospecific locking or blocking of the OH group of the enantiomeric alcohol, opening of the acetonide ring and cyclization of the compound obtained. (CF DRAWING IN BOPI) The present invention also relates to the compounds thus obtained. |
