- Development of 3-alkyl-6-methoxy-7-hydroxy-chromones (AMHCs) from natural isoflavones, a new class of fluorescent scaffolds for biological imaging
-
Starting from 7-hydroxyisoflavones, we developed a new class of fluorescent scaffolds, 3-alkyl-6-methoxy-7-hydroxy-chromones (AMHCs, MW ~ 205.19, λab ~ 350 nm, λem ~ 450 nm) via a trial and error process. AMHCs have the advantages of being a small molecular moiety, having strong fluorescence in basic buffers, reasonable solubility and stability, non-toxicity, and are conveniently linked to pharmacophores. AMHCs were successfully used in fluorescence microscopy imaging of cells and tissues. This journal is

- A convenient one-pot synthesis of 7-hydroxy-isoflavones from resorcinol with substituted phenylacetic acids
-
A mild and highly efficient one-pot synthesis of 7-hydroxy-isoflavones is reported. The acylation of resorcinol with various phenyl acetic acids in molten zinc chloride affords an intermediate deoxybenzoin which without isolation is subjected to cyclization with N,N-dimethylformamide in the presence of boron trifluoride diethyl etherate and methanesulfonyl chloride to afford the 7-hydroxy-isoflavone without the formation of any by-product.
