摘要:
In the presence of KF-Al2O3 as a solid base, 2-nitrofluorene 1 condensed with aromatic aldehydes 2a-f in methanol to give 2-nitrodibenzofulvenes 3a-f in high yield. The para-substituted acetophenones 4a-f reacted with cinnamic aldehyde to give 1, 5-diaryl-2, 4-pentadien-1-ones 6a-f in moderate yield.
