2-(α-Hydroxybenzyl)-2-methoxycoumaran-3-ones are major products in the alkaline hydrogen peroxide oxidation (AFO reaction) of 2′-hydroxy-α-methoxychalcones containing a phloroglucinol type A-ring, while flavonols predominate in the oxidation prod

Both 5 : 8 : 2' trimethoxyflavone (I ; R = Me) and the 2' : 3' : 6'- isomer(II; R = Me) yield 5 : 6 : 2' - trihydroflavone (IV : R = H) on demethylaction by hydridic acid. This result confirms previous views (see Gallagher et., al., J., 1953, 3770) t

The formation of 3-phenylthioinden-1-ones by cyclisation of α-substituted β-phenylthio-cis-cinnamic acids with phosphorus pentoxide is described; results obtained using other cyclising reagents are also reported.

The Auwers synthesis of 2-acylcoumaran-3-ones (III) freom the corresponding o-acyloxy-ω-chloroacetophenones (I; X = CI) is shown almost certainly to involve an internal Claisen condensation of the Baker-Venkataraman type. This result confirms an ear
