Microwave-assisted synthesis and antimicrobial evaluation of novel pyrazolines

A series of 6-(5-aryl-4,5-dihydro-1 H-pyrazol-3-yl)-2,2-dimethylchroman-7-ol and 6-(5-aryl-4,5-dihydro-1 H-pyrazol-3-yl)-2,2-dimethyl-chroman-5-ol derivatives have been synthesized from the corresponding chalcones and hydrazine hydrate in the presence of

BF3-Et2O mediated biogenetic type synthesis of chromanochalcones from prenylated chalcones via a regioselective cyclization reaction

In continuation of our program on synthetic chalcones, we have developed a simple and convenient method for the synthesis of chromanochalcones from prenylated chalcones in high yields by regioselective cyclization using BF3-Et2O.

A facile synthesis of acetyl-hydroxy-2, 2-dimethylchromans and 2,2- dimethyl-2H-3,4-dihydropyranoflavanones - Dihydro mixtecacin, atalantoflavone dimethyl ether and racemoflavone dimethyl ether

Synthesis of acetyl-hydroxy-2, 2-dimethyl chromans by thermal-Fries rearrangement of acetoxy-2, 2-dimethylchromans has been described. The reaction of acetyl-hydroxy chromans (2, 4 and 6) with aryl aldehyde in the presence of aqueous ethanolic potassium h

13C Nuclear Magnetic Resonance Studies on Pyrano- and Dihydropyrano-1,3-diphenylprop-2-enones

The 13C NMR spectra of 19 differently substituted pyrano- and dihydropyrano-1,3-diphenylprop-2-enones were recorded and the results are discussed.The data will be useful in the identification of new and natural chalcones. Key Words: Chalcones - 1,3-Diphen

CINNAMOYLATION OF CHROMANS: FORMATION OF FLAVONOIDS AND NEOFLAVONOIDS

Cinnamoylation of chroman 1 with 4 in presence of fused zinc chloride and phosphorus oxychloride gave chalcone 8 and with acids 5-7, the chalcones 9-11 and dihydrocoumarins 15-17 respectively.A similar reaction of chroman 2 with acids 4 and 5 afforded the

Boron Trifluoride Etherate Catalysed Rearrangement of Dihydropyranochalcone Epoxides: Synthesis of Dihydropyranoisoflavones and Their Dehydro-analogs

6-Acetyl-7-hydroxy-2,2-dimethylchroman (I) and 6-acetyl-7-methoxy-2,2-dimethylchroman (II) on condensation with the arylaldehydes (IIIa-d) give the dihydropyranochalcones (IVa-f).The O-benzylated chalcones (Va-f) are oxidised with alkaline hydrogen peroxi
