A new synthesis of flavones and pyranoflavone by intramolecular photochemical Wittig reaction in water

A new synthetic approach toward the synthesis of flavones and pyranoflavone has been developed by light induced intramolecular photochemical Wittig reaction in water onto aryloxycarbonyl groups and suitably substituted phosphonium bromides sans any phase transfer catalyst or promoter.

HETEROCYCLES FROM DIACETYL PHENOLS: SYNTHESIS OF BENZODIPYRANS, ACETYLCHROMENES AND PYRANOBENZISOXAZOLES

Novel and facile syntheses of benzodipyrans, acetylchromenes and pyranolbenzisoxazoles from 2,4- and 4,6-diacetylresorcinols have been described.Regioselective condensations and reductions have been used as the key steps.

Enolates of Diacetylresorcinols: Application to Synthesis of Benzodipyrans

Four benzodipyrans namely, 2,2,8,8-tetramethyl-2H,8H-benzodipyrans (7/8), 2,8-diphenyl-4H,6H-benzodipyran-4,6-dione (9) and 2,8-diphenyl-4H,10H-benzo dipyran-4,10-dione (10) have been synthesised.The

Homobiflavonoids from 5-Acetyl- and 3-Acetyl-resacetophenones

Reaction of 5- and 3-acetyl-resacetophenones with formaldehyde under acidic conditions yields the bis-methylene derivatives (V) and (XIa), respectively in good yields.These have been condensed with benzaldehyde to obtain the corresponding chalkones, which

Synthesis of Some Benzodipyrones from 4,6-Diacetylresorcinol

Some α- and γ-benzodipyrones have been prepared in very good yield from 4,6-diacetylresorcinol (I) and characterised by their spectral data.
