Synthesis of acyclic bayin analogs was reported. The substituted flavones were obtained by starting from 2,4-dihydroxyacetophenone, after monobenzylation, Claisen rearrangement, Aldol condensation and I2/DMSO/H2SO4 cyclization. Claisen rearrangement was used to introduce the 8-substituted side chain before or after the formation of flavone ring with high yield. Allylic side chain was modified to give six bayin analogs in which compound I has a free 7-hydroxy group.
