摘要：
[graphic not available: see fulltext]
The reaction of chromone-3-carboxylic acid with indoles in boiling ethanol proceeds as a 1,4-nucleophilic addition with successive opening of the pyrone ring and decarboxylation to afford a series of previously unknown trans-indolyl chalcones in 27–60% yields.
