Abstract
But-1-enyl(methyl)maleic anhydride (4) has been synthesised and shown to act as an efficient (55% incorporation) precursor of the cyclononadienes, glauconic and glaucanic acids, in Penicillium purpurogenum. Base-catalysed dimerisation of compound (4) yields 5% of an epimer of glaucanic acid.Keywords
