The enzymatic conversion products of stearoylvelutinal in injured fruit bodies of Lactarius scrobiculatus have been investigated. Two sesquiterpene aldehydes not previously reported as natural products were isolated in addition to known sesquiterpenes. The structures were determined by spectroscopy combined with molecular mechanics calculations, and chemical transformation into known compounds.

ester of velutinal (i.e. compound 2b and 2a, respectively) as the only sesquiterpenoid. When the fruit bodies are injured the esters are enzymatically converted into sesquiterpene furans, mono- and di-aldehydes, and lactones, which have been isolated and their structures elucidated. These compounds have been submitted to conformational analysis by molecular mechanics and 1H NMR in order to make correct
