Separation of isomers of furo (3,4-C) pyridine derivatives
This invention relates to a method for the separation of stereoisomers of 7-hydroxy-furo[3,4-c]pyridine derivatives of the formula STR1 wherein R3, R4 and R6 represent various substitutents, which comprises reacting a fully O-acetylated monosaccharide halogenide with a racemate of the selected 7-hydroxy-furo[3,4-c]pyridine derivative, to form the (+) and (-) (O-acetylated monosaccharide) (furo[3,4-c] pyridine 7-yl derivative) ethers, then separating the (+) and the (-) ethers by selective crystallization, in an hydroalcoholic medium, either of the acetylated forms or of the corresponding desacetylated forms and, finally, working up each of the separated derivatives by the usual routes. The compounds are known pharmaceuticals.
