Velleral
Chemical compound / From Wikipedia, the free encyclopedia
Velleral (2,2,8-trimethyl-3,3a,8,8a-tetrahydro-1H-azulene-5,6-dicarbaldehyde) is a sesquiterpene dialdehyde found in certain mushrooms, like Lactarius torminosus[1] and Lactarius vellereus, after which it was named. The compound is thought to be part of a chemical defense system that protects the mushrooms against predation.[2] First isolated in 1969,[3] and characterized structurally in 1973,[4] velleral has antimicrobial activity.[5] Several syntheses have been devised.[6][7][8]
