A group of 3,5-diaryl-2-pyrazoline and hydrazone derivatives was prepared via the reaction of various chalcones with hydrazide compounds in ethanol. Twenty original compounds were synthesized. Ten of these original compounds have a pyrazoline structure, n

Chalcones, intermediates in flavonoid biosynthesis, can exhibit antibacterial, antiproliferative, and anti-inflammatory properties. Chalcones contain two benzene rings and both hydroxylated and methoxylated analogs are frequently produced by hydroxylases and O-methyltransferases in plant biosynthetic pathways. Assignments of NMR peaks in the spectra of hydroxylated and/or methoxylated chalcones can help in identifying novel chalcone derivatives isolated from natural sources by referencing these data against NMR spectra obtained from known chalcones. We report here the syntheses of 20 chalcones and complete assignments of 1H and 13C NMR spectra. Copyright
Two Syntheses of 7,2'-Dimethoxyisoflavone
Rani, Indu
, p. 361 - 362 (2007/10/02)
7,2'-Dimethoxyisoflavone (V) has been synthesised by two routes: (i) by direct oxidative rearrangement of 2'-hydroxy-2,4'-dimethoxychalkone; and (ii) by treatment of 2'-benzyloxy-2,4'-dimethoxychalkone epoxide (III) derivable from I, with BF3-etherate to
