Abstract

... 1. Selectivity of Cyclization of 1,3-Diarylallylic Cations 7 into Indenes 8 and 9. ... figure Scheme 2. Synthesis of 1,3-Diarylallylic Alcohols 6 Using Knoevenagel or Aldol-Based ... indicates that cyclization is favored through the unsubstituted phenyl ring over the p-methoxyphenyl ring. ...
