To find new and better antivascular agents for cancer therapy, a series of combretastatin A4 (CA4) analogs were prepared from 1, 3-diaryl-2-nitroprop-1-enes (6–12) obtained in a two- step synthesis from appropriate arylaldehydes and 2-aryl-1-nitroethanes (4 or 5). Treatment of these 1, 3-diaryl-2-nitroprop-1-enes 6–12 by sodium azide in DMSO yielded the targeted compounds. The synthesized 1, 2, 3-triazoles disubstituted in 4-and 5-positions by one ...
