A Facile Synthesis of Isopongaflavone, Atalantoflavone Dimethylether, Racemoflavone Dimethylether and their Analogues

A convenient route to pyranoflavones (natural and synthetic) from acetyl hydroxy chroman via the corresponding analogues by the use of Claisen condensation in the key step is reported.Keywords: 2-Aryl-8,8-dimethyl-6,7-dihydro-4H,8H-benzodipy

PRENYLATED COMPOUNDS FROM ATALANTIA RACEMOSA: ISOLATION AND SYNTHESIS OF TWO PYRANOFLAVONES

A re-examination of the aerial parts of the plant Atalantia racemosa led to the isolation of two new pyranoflavones, namely atalantoflavone and racemoflavone .The structures have been confirmed by the synthesis of methyl ethers of atalantoflavone and racemoflavone. besides the pyranoflavones, seven biogenetically related coumarin derivatives namely, xanthyletin, luvangetin, recemosin, xanthotoxin, umbelliferone, rutarin, rutaretin and a triterpene, friedelin have been isolated.
