摘要:
The reaction of flavanone pinostrobin with dibromoalkanes in acetone in the presence of potassium carbonate followed the path of retro-Michael addition - D-alkylation and resulted in the formation of the respective 2-(bromoalkoxy)chalcones. Treatment of the latter with sodium azide gave the respective azides, which were highly active in the Du-catalyzed 1,3-dipolar cycloaddition reaction. The reaction of these azides with 6-substituted 7-ethynylcoumarins gave coumarin-chalcone hybrids containing a 1,2,3-triazole linker.
