Orcinol synthesis

Orcinol was first prepared by dehydroacetic acid, a conversion that involved ring-opening of the pyrone to a triketone. This early experiment helped establish the rich condensation chemistry of polyketides. It can be obtained by fusing extract of aloes with potash, followed by acidification. It undergoes O-methylation … See more Orcinol is an organic compound with the formula CH3C6H3(OH)2. It occurs in many species of lichens including Roccella tinctoria and Lecanora. Orcinol has been detected in the "toxic glue" of the ant species See more Orcinol is also found in shale oil produced from Kukersite oil shale. It is the main water-soluble phenol in the oil, and has been extracted and refined industrially by Viru Keemia Grupp. See more • Orcinol 2-monooxygenase • Orsellinate decarboxylase See more WebOct 10, 2024 · Due to its pathogenicity rhamnolipid synthesis by this species is viewed as being commercially nonviable, as such there is a significant focus to identify alternative producers of rhamnolipids. ...
