Abstract
The reaction of 1,2-diphenylethanedione ("benzil'') with cyclopentadiene in the presence of sodium methoxide unexpectedly afforded a novel 2,3,7-triph enyl derivative of the bicyclic cyclopenta[c]pyran. The structure was eluci dated by physical methods (IR, UV/VIS, H-1-NMR, C-13-NMR, MS) and a single- crystal X-ray analysis.
