A new diterpene with two polymorphic modifications from a marine alga
A new diterpene, β-dictalediol monoacetate ( 1 ), has been isolated from a brown alga Dictyota sp. X-ray crystal structure studies of 1 have revealed the existence of two polymorphic modifications: dimorph 1a in a chair/boat/chair conformation, and dimorph 1b in a chair/chair/chair conformation.

| Zusammenfassung: | A new diterpene, β-dictalediol monoacetate (

), has been isolated from a brown alga
Dictyota sp.
X-ray crystal structure studies of
1
have revealed the existence of two polymorphic modifications: dimorph
1a
in a chair/boat/chair conformation, and dimorph
1b
in a chair/chair/chair conformation.
A new diterpene, β=dictalediol monoacetate (
