资源简介：
Condensation between truxenone (8) and the lithium acetylide derived from 0.9, 2.5, and 5.0 equiv of 1-ethynyl-2-(phenylethynyl)benzene produced the corresponding benzannulated enediynyl alcohol 9, diol 14, and triol 16, respectively. On exposure of these alcohols to thionyl chloride, cascade cyclization reactions occurred to furnish polycyclic compounds 13, 15, and 18 in a single operation. The unusual architectures of these polycyclic compounds were established by NMR spectroscopy and X-ray structure analyses.
