Synthesis of diindeno-fused 4H-cyclopenta[def]phenanthren-4-ones and related compounds via benzannulated enediynyl propargylic alcohols

(Chemical Equation Presented) Treatment of propargylic diols 5-7 with thionyl chloride promoted a cascade sequence of reactions leading to dichlorides 10-12 and, after reduction with tributyltin hydride, the diindeno-fused 4H-cyclopenta[def]phenanthrenes
