Abstract :
Isoflavan-4-ol has been synthesized quantitatively from the reduction of isoflavone in the presence of Pd/C and ammonium formate under N2 atmosphere. Isolation of cis- and trans-isomers was achieved by flash column chromatography and each enantiomer was separated by Sumi-Chiral column chromatography. Absolute configurations of four stereoisomers were determined by circular dichroism spectroscopy.
