Synthesis of 3-(2-Olefinbenzyl)-4H-chromen-4-one through Cyclobenzylation and Catalytic C-H Bond Functionalization Using Palladium(II)

An efficient strategy for synthesizing 3-(2-olefinbenzyl)-4H-chromen-4-one in two steps was developed. The first step is a cyclobenzylation reaction between (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one and benzyl bromide to produce homoisoflav

Isomerisation of 3-Benzylidene-4-chromanones in Presence of Alkali

3-Benzylidene-4-chromanones (Ia-d) having 7-methoxy, 7-benzyloxy- or 5,7-dimethoxy groupings in ring-A undergo alkali isomerisation to yield both the corresponding 3-benzyl-4-chromones (IIa-d) and 3-methylflavones (IIIa-d).Hence both the types of isomeris
