| titleOfInvention |
Preparation of trans-fused 3,3a,8,12b-tetrahydro-2h-dibenzo[3,4:6,7]cyclohepta[1,2-b]furan derivatives |
| 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. |
