Novel isotactic polymethoxy-1-alkenes 1-4 were isolated from tolytoxin-producing blue-green algae belonging to the family Scytonemataceae. Scytonema mirabile produced 1 and 2, whereas 3 and 4 were isolated from S. burmanicum. The gross structures and relative stereochemistries were determined by mass and NMR spectral analyses. The absolute configurations of 1-4 were established by direct comparison with optically active synthetic samples.
