Isolation and structure (X-ray analysis) of the orsellinate of armillol, a new antibacterial metabolite from Armillaria mellea
Abstract
The structure of the orsellinate of armillol (2a), a new member of the protoilludane group and one of several sesquiterpenoid esters isolated from Armillaria mellea, was established by spectral and chemical means and confirmed by single-crystal X-ray analysis of its oxidation product, the hydroxy-aldehyde (5a).
