Microwave assisted selective synthesis of (E)-1-(4-Chloro-7-hydroxy-2-aryl-2H-chromen-6-yl)-3-arylprop-2-en-1-ones and their antimicrobial activity
摘要:
A series of new (E)-1-(4-chloro-7-hydroxy-2-aryl-2H-chromen-6-yl)-3-arylprop-2-en-1-ones (2a-2f) have been synthesized by selective mono cyclization of 4,6-dicinnamoyl resorcinols (1a-1f) using Vilsmeier-Haack reagent under conventional heating and microwave irradiation. The structures of the synthesized compounds have been elucidated by elemental analysis, IR, H-1 NMR, C-13 NMR and Mass spectral data. The synthesized compounds were tested in vitro for antimicrobial activity.
