The two new diarylheptanoids, 1,7-bis(4-hydroxyphenyl)-1,4,6 (l) and aecrogenin G (2) were Synthesized starting from 4-hydroxybenzaldehyde (3) and acetone
Four 8, 8'-biflavones were synthesized by the iodination of 2'-hydroxychalcones at 8-position in I-2-H2SO4-DMSO system as the key step followed by coupling under Ullmann reaction conditions.
