Methanolysis of the diterpenoid aldehyde:anhydride, fujenal, catalysed by tetracyanoethylene afforded C-6:C-7 methoxylactones whilst the addition of methyl magnesium bromide to fujenal afforded a 6,7-lactone but with an cis A/B ring junction; the structures of these products were established by X-ray crystallography.
