  • Preparation of trans-fused 3,3a,8,12b-tetrahydro-2H-dibenzo[3,4:6,7]cyclohepta[1,2-b]furan derivatives
    Publication number: 20050228043
    Abstract: The present invention concerns processes for the preparation of each of the 4 diastereomers of formula (I) in stereochemically pure form from either of two enantiomerically pure precursors. The tetracyclic ringsystem having trans-fused five and seven membered rings is formed in an acid-catalysed cyclization reaction. The invention further relates to the thus obtained cis-fused tetracyclic alcohol intermediates, the methanamine end-products, the methanamine end-products for use as a medicine, in particular as CNS active medicines.
    Type: Application

  • Preparation of cis-fused 3,3a,8,12b-tetrahydro-2h-dibenzo[3,4:6,7]cyclohepta[1,2-b]furan derivatives
    Publication number: 20050033067
    Abstract: The present invention concerns a process for preparing each of the 4 individual diastereomers of formula (I) in stereochemically pure form from a single enantiomerically pure precursor. The tetracyclic ringsystem having cis-fused five and seven membered rings is formed in a base-catalysed cyclization reaction. The invention further relates to the thus obtained cis-fused tetracyclic alcohol intermediates and methanamine end-products, and the methanamine end-products for use as a medicine, in particular as CNS active medicines.
