title: Structure and conformation of two new dolabellane-based diterpenes from Dictyota sp.
abstract: Two new dolabellane derivatives (5 and 6) have been isolated from a Dictyota sp. and their structure, including absolute configuration, has been determined on the basis of spectral studies and chemical correlations.
