  • Publication number: 20100048920
    Abstract: Processes for preparing racemic mixtures of 5,7,3?,4?-tetra-O-benzyl-(±)-catechin and (±)-epicatechin involves (i) condensing 2-hydroxy-4,6-bis(benzyloxy)-acetophenone and 3,4-bis(benzyloxy)benzaldehyde, cyclizing the resulting compound, oxidizing the resulting compound; (ii) dihydroxylating (E)-3-(3?,4?-bis(benzyloxy)phenyl)prop-2-ene-1-ol and reducing the 1,2-diol; or (iii) coupling 3,5-bis(benzyloxy)phenol with (E)-3,5-bis(benzyloxy)-2-(3?,4?-bis(benzyloxy)phenyl)allyl)phenol and cyclizing the resulting chalcone. A process for preparing the benzylated epimers of catechin and epicatechin involves seven steps. 3,4-Bis(benzyloxy)benzaldehyde is coupled with 2-hydroxy-4,6-benzyloxy-acetophenone to form a chalcone. The chalcone is selectively reduced to an alkene. The phenolic group of the alkene is protected. The protected alkene is asymetrically dihydroxylated. The resulting compound is deprotected, cyclized, and finally hydrolyzed.

  • Publication number: 20040049049
    Abstract: A stereoselectively method of preparing a 1,2-disubstituted cycloalkyl, such as aminocycloalkyl ether compounds, from a trans-1,2-disubstituted cycloalkyl or a cis-2-substituted cycloalkanol. For example, a stereoselective method of preparing 1R-(3R-hydroxypyrrolidin-1-yl)-2R-(2-phenylethoxy)-cyclohexane from 1R,2R-cyclohexanediol or from meso-cis-1,2-cyclohexanediol is described. Aminocycloalkyl ethers, such as 1R-(3R-hydroxypyrrolidin-1-yl)-2R-(2-phenylethoxy)-cyclohexane, can be used to treat cardiac disease.
