Stereoselective route to produce tris-O-substituted-(E)-1-(3,5-dihydroxyphenyl)-2-(4-hydroxyphenyl)ethene, an intermediate in the synthesis of trans-resveratrol |
摘要 |
The present invention relates to a new stereoselective method for the preparation of tris-O-substituted-(E)-1-(3,5-dihydroxyphenyl)-2-(4-hydroxyphenyl)ethene derivative of the formula (I) which is a key intermediate in the synthesis of trans-resveratrol (I, R2=R2=R3=H). The invention also provides a method for the exclusive synthesis of trans-isomer of compounds of formula (I) without any contamination of cis-isomer.
