Synthesis of the α,β-unsaturated δ-lactones (+)-anhydrocalopin and (+)-dehydrocalopin

During our investigations on the calopin group of mushroom metabolites, a synthesis of 3,4-disubstituted α,β-unsaturated δ-lactones has been developed. It was applied to the synthesis of optically active dehydrocalopin (2) and anhydrocalopin (3).
