Synthesis of 4-Aryl-3-(2-chromonyl)-2-pyrazolines by the 1,3-Dipolar Cycloaddition of 2-Styrylchromones with Diazomethane

The first reported 1,3-dipolar cycloaddition of 2-styrylchromones with diazomethane afforded 4-aryl-3-(2-chromonyl)-2-pyrazolines. However, 3-aryl-4-(2-chromonyl)-1-pyrazolines have been also found as minor products of this reaction. These two series of p

1,5-Diphenylpenta-2,4-dien-1-ones as potent and selective monoamine oxidase-B inhibitors

A series of (2E,4E)-1-(2-hydroxyphenyl)-5-phenylpenta-2,4-dien-1-ones (3a-r) and (2Z,4E)-3-hydroxy-1-(2-hydroxyphenyl)-5-phenylpenta-2,4-dien-1-ones (6a-l) were synthesized and evaluated in vitro as inhibitors of the two human Monoamine oxidase (hMAO) iso

Efficient syntheses of new polyhydroxylated 2,3-diaryl-9H-xanthen-9-ones

A large number of hydroxylated 2,3-diaryl-9/i-xanthen-9ones have been synthesised by two different approaches, starting either from 3-brom.o-2-m.elhyl-4H-ch:rom.en-4-one or from. (E)-3-brom.o-2-styryl-4H-chrom. en-4-ones. The former method involves Heck r

A novel and efficient route for the synthesis of hydroxylated 2,3-diarylxanthones

A novel, efficient and general route for the synthesis of hydroxylated 2,3-diarylxanthones is described. 3-Bromo-2-styryl-chromone, the key intermediate of this synthesis, is obtained by a Baker-Venkataraman rearrangement of the appropriate 2′-cinnamoylox
