Abstract

The reactivity of the title compounds with different nucleophiles has been checked and it was shown that products from reaction with sodium phenylthiolate result from an elimination-addition process in which protoanemonin is the key intermediate. The synthesis of (-)-(R)-β-angelica lactone is reported for the first time. © 1983.
