cis-trans Isomerization of silybins A and B
Original language description
Methods were developed and optimized for the preparation of the 2,3-cis- and the 10,11-cis-isomers of silybin by the Lewis acid catalyzed (BF3 center dot OEt2) isomerization of silybins A (1a) and B (1b) (trans-isomers). The absolute configuration of alloptically pure compounds was determined by using NMR and comparing their electronic circular dichroism data with model compounds of known absolute configurations. Mechanisms for cis-trans-isomerization of silybin are proposed and supported by quantum mechanical calculations.
