| titleOfInvention |
Asymmetric synthesis of hexahydrodibenzofurans by stereospecific inversion of ortho substituted 2-phenylcyclohexanols |
| abstract |
This invention relates to the stereospecific process for the preparation, separation and purification of hexahydrodibenzofurans which are used in the preparation of the 5HT3 compounds. More specifically, the present invention relates to a process for the preparation of substantially optically pure cishexahydrodibenzofuran compounds including at least two chiral fused ring centers which comprises the acidic catalyzed stereospecific ring closure by the intra-molecular inversion of a gamma, i.e. 2', carbon atom of a 2-[(2'-leaving group)cycloalkyl]phenol. |
