Abstract
AbstractMarine dinoflagellates produce remarkable organic molecules, particularly those with polyoxygenated long‐carbon‐chain backbones, namely super‐carbon‐chain compounds (SCCCs), characterized by the presence of numerous stereogenic carbon centers on acyclic polyol carbon chains. Even today, it is a challenge to determine the absolute configurations of these compounds. In this work, the planar structures and absolute configurations of two highly flexible SCCCs, featuring either a C69‐ or C71‐linear carbon backbone, gibbosols A and B, respectively, each containing thirty‐seven stereogenic carbon centers, were unambiguously established by a combined chemical, spectroscopic, and computational approach. The discovery of gibbosols A and B with two hydrophilic acyclic polyol chains represents an unprecedented class of SCCCs. A reasonable convergent strategy for the biosynthesis of these SCCCs was proposed.
