Homoisoflavonoids
Homoisoflavonoids (3-benzylidenechroman-4-ones) are a type of phenolic compounds occurring naturally in plants. Chemically, they have the general structure of a 16-carbon skeleton, which consists of two phenyl rings (A and B) and heterocyclic ring (C). Synthesis Homoisoflavones can be synthetized from 2'-hydroxydihydrochalcones. Homoisoflavanones can be synthetized from 3,5-methoxy phenols via chroman-4-one in three steps or from phloroglucinol. ;Conversion Homoisoflavanes can be obtained from the conversion of homoisoflavonoids. Natural occurrences The homoisoflavonoids portulacanones A, B, C and D can be found in '' Portulaca oleracea'' (common purslane, Caryophyllales, Portulacaceae). The 3,4-dihydroxyhomoisoflavans sappanol, episappanol, 3'-deoxysappanol, 3'-O-methylsappanol and 3'-O-methylepisappanol can be found in ''Caesalpinia sappan''. The homoisoflavones scillavones A and B can be isolated from the bulbs of ''Scilla scilloides'' ('' Barnardia japonica'') ...
