(+)-Ovalifoliene and (–)-hanegokedial, two novel sesquiterpenoids of the ent-2,3-seco-alloaromadendrane skeleton from the liverwort Plagiochila semidecurrens
Abstract
Two novel sesquiterpenoids have been isolated from the liverwort Plagiochila semidecurrens, and their structures and absolute configurations have been shown to be (1) and (2), ent-2,3-seco-alloaromadendrane derivatives.
